He was the president of the German Jewish cantors' and teachers' associations as well as of the Frankfurt section of the B'nai B'rith Lodge. He emigrated to the USA in 1939. Joseph B. Levy was the author of the prayer book "Shaarei Tefillah", of several school books and the editor of a collection of Gabriel Riesser's writings
On intrinsic ultracontractivity of perturbed Levy processes and applications of Levy processes in actuarial mathematics
No full textIn this thesis, we study certain aspects of Levy processes and their applications. In the first part of this thesis, we study the applications of Levy processes in actuarial mathematics. Our topics are closely related to the generalized Ornstein-Uhlenbeck processes. We investigate their intimate relationships with the exponential functionals of Levy processes, which enable us to develop efficient semi-analytical algorithms to solve the pricing and risk management problem of certain exotic variable annuity products. In particular, we consider two variable annuity products with guaranteed benefits, the Guaranteed Minimum Accumulation Benefit (GMAB) and the Guaranteed Minimum Withdrawal Benefit (GMWB). For the first one, we develop efficient semi-analytical algorithms to compute its risk measures and hedging costs to solve the risk management problem of the rider. For the other one, we consider pricing the rider. We identify the Laplace transforms of the GMWB rider's risk-neutral values analytically, which leads to efficient solutions to its pricing problem.
In the second part, we consider the intrinsic ultracontractivity of certain Levy processes under nonlocal perturbations. More precisely, we establish the intrinsic ultracontractivity of the Laplacian (corresponding to Brownian motions) and the fractional Laplacian (corresponding to symmetric -stable processes) perturbed by a class of nonlocal operators. Conditions on the nonlocal perturbations are given in order to guarantee that the perturbed operators are intrinsically ultracontractive in general bonded open sets. The methods we use are probabilistic. Essentially, the methods rely on the heat kernel estimates of the fundamental solutions of the operators as well as the Levy systems of the corresponding processes.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2019-12-01The student, Bingji Yi, accepted the attached license on 2017-10-14 at 22:59.The student, Bingji Yi, submitted this Dissertation for approval on 2017-10-14 at 23:05.This Dissertation was approved for publication on 2017-10-23 at 09:46.DSpace SAF Submission Ingestion Package generated from Vireo submission #11686 on 2018-03-13 at 09:55:24Made available in DSpace on 2018-03-13T15:21:04Z (GMT).

Popularity-similarity random SAT formulas
No full text[EN]In the last decades, we have witnessed a remarkable success of algorithms solving the Boolean Satisfiability problem (SAT) on instances encoding application or real-world problems arising from a very diverse number of domains, such as hardware and software verification, planning or cryptography. These algorithms are the so known Conflict-Driven Clause Learning (CDCL) SAT solvers. Interestingly enough, the reasons for the success of these solvers on this diverse range of problems are not completely understood yet.
A common issue when facing this open challenge is the heterogeneity of this set of benchmarks. Another problem is the limited number of existing instances. In this context, random models of SAT formulas capturing features shared by the majority of these application benchmarks become crucial, for both theoretical and practical purposes. On the one hand, it is undoubtedly necessary to have random models where theoretical properties, like hardness, can be studied. Therefore, realistic random SAT models may contribute to explain the success of these solvers on these industrial problems. On the other hand, the limited number of benchmarks and their hardness in practice makes the evaluation of new solving techniques a costly task. Therefore, these realistic random SAT generators can provide an unlimited number of pseudo-industrial random SAT instances with some desired properties.
In this work, we present a random SAT instances generator based on the notion of locality. This notion is complementary to the popularity of variables, which is present in the scale-free structure, observable in actual application problems and achievable by previous generators. Our random SAT model combines both locality and popularity, and we show that they are two decisive dimensions of attractiveness among the variables of a formula, and how CDCL SAT solvers take advantage of them. Locality is closely related to the community structure, another important feature of application SAT benchmarks, which is indirectly achieved by this model. To the best of our knowledge, this is the first random SAT model that generates both scale-free structure and community structure at once.This work is partially supported by the EU H2020 Research and Innovation Programme under the LOGISTAR

"Asset Poverty in The United States: Its Persistence in an Expansionary Economy"
No full textFrom this paper's Preface, by Dr. Dimitri B. Papadimitriou, President: Economic growth and a rising stock market in the 1990s gave the impression that everyone was accumulating wealth and asset poverty rates were declining. The impression was supported by the official, income-based poverty measure, which exhibited a sharp decline. According to Senior Scholar Edward N. Wolff and Research Scholar Asena Caner, poverty measures should include wealth as well as income. Their study of asset poverty in the United States between 1984 and 1999 focuses on the lower end of the wealth distribution and shows that asset poverty rates did not decline during the period studied, and that the severity of poverty increased. It also shows that asset poverty is much more persistent than income poverty.

"The Ownership Society: Social Security Is Only the Beginning"
No full textFrom this paper's Preface, by Dr. Dimitri B. Papadimitriou, President: As his new term begins, President Bush has been trying to focus his domestic agenda on what he calls the Òownership society,Ó a sweeping vision of an America in which more citizens would hold significant assets and be free to make their own choices about providing for their health care and retirement, and educating their children. L. Randall Wray, who has written for the Levy Institute on many topics, evaluates the premises and logic of this program in this new public policy brief. Wray points out that much of the history of the Western world since the advent of liberalism has been marked by a gradual rise in the power of those who lack property. Some of the milestones in this progression include universal suffrage, regulation of business, and progressive taxation. BushÕs ownership society proposals, according to Wray, would result in a partial reversal of the progress of the last 250 years. The reason is that, while BushÕs plans would undoubtedly increase the choices and power of those who have property, they would fail to democratize ownership. Many gains to the wealthy would come at the expense of the poor, the sick, and the elderly. Consider, for example, the condition of the nationÕs private pension system. Increasingly, firms are switching from defined-benefit to definedcontribution plans. This development would seem on its surface to favor the establishment of a new class of stockholders, empowered and holding a larger stake in the system. But, as Wray demonstrates, retirement accounts and other assets just do not add up to a substantial amount for most Americans. This means that most citizens have much to lose indeed from attacks on Social Security and the erosion of the traditional pension system. Much as the safety net for the poor has largely vanished since the Reagan years, the bread-and-butter benefits and rights of the middle class are now threatened by the ownership-society agenda. To many, the claim made by Republicans that all should take responsibility for their wellbeing rings true. But it is important to keep in mind the real alternative to public benefits for the middle class: a society in which success would depend largely upon luck, inheritances, or charity. A society that forces individuals to read their future in their Microsoft Money files inevitably creates a class of nonowners who are insecure and lack independent means. Ironically, this runs up against the aims of those who sincerely hope for a world in which more have the opportunity to become rich: moving upward often brings some setbacks along the way, which might be fatal in a world of reduced bankruptcy protection, disability and medical benefits, and educational aid.
