Kuznetsov independence for interval-valued expectations and sets of probability distributions: Properties and algorithms
No full textKuznetsov independence of variables X and Y means that, for any pair of bounded functions f(X) and g(Y), E[f(X)g(Y)]=E[f(X)] *times* E[g(Y)], where E[.] denotes interval-valued expectation and *times* denotes interval multiplication. We present properties of Kuznetsov independence for several variables, and connect it with other concepts of independence in the literature; in particular we show that strong extensions are always included in sets of probability distributions whose lower and upper expectations satisfy Kuznetsov independence. We introduce an algorithm that computes lower expectations subject to judgments of Kuznetsov independence by mixing column generation techniques with nonlinear programming. Finally, we define a concept of conditional Kuznetsov independence, and study its graphoid properties
The Improved (G’/G)-Expansion Method for the (2+1)-Dimensional Modified Zakharov-Kuznetsov Equation
Get PDFwe apply the improved (G′/G)-expansion method for constructing abundant new exact traveling wave solutions of the (2+1)-dimensional Modified Zakharov-Kuznetsov equation. In addition, G″+λG′+μG=0 together with b(α)=∑q=−wwpq(G′/G)q is employed in this method, where pq (q=0,±1,±2,…,±w), λ and μ are constants. Moreover, the obtained solutions including solitons and periodic solutions are described by three different families. Also, it is noteworthy to mention out that, some of our solutions are coincided with already published results, if parameters taken particular values. Furthermore, the graphical presentations are demonstrated for some of newly obtained solutions
Pavelius Kuznetsov & Levenstein 1988
No full textPavelius Kuznetsov & Levenstein, 1988 Type species: Pavelius uschakovi Kuznetsov & Levenstein, 1988 Generic diagnosis (emended). Prostomium without lobes or glandular ridges. Buccal tentacles smooth. Four pairs of branchiae. Notochaetae in segment II present, followed by fifteen thoracic chaetigers. Twelve thoracic uncinigers. Two intermediate uncinigers. Males with one pair of nephridial papillae above notopodia of first thoracic unciniger. Remarks. The generic diagnosis was emended to accommodate our findings in the newly described species. The genus was described lacking notopodial rudiments, which we found in the intermediate uncinigers and first abdominal unciniger. The large nephridial papillae above the notopodia of the first thoracic unciniger only seem to occur in male specimens. We do not follow Jirkov (2001, 2011), who suggested to synonymize Pavelius with Phyllocomus Grube, 1878. Phyllocomus is characterized by strongly modified branchiae and a very large number of abdominal uncinigers.Published as part of Reuscher, Michael G. & Fiege, Dieter, 2016, Ampharetidae (Annelida: Polychaeta) from cold seeps off Pakistan and hydrothermal vents off Taiwan, with the description of three new species, pp. 197-208 in Zootaxa 4139 (2) on page 204, DOI: 10.11646/zootaxa.4139.2.4, http://zenodo.org/record/26211
New (G′/G)-expansion method and its application to the Zakharov-Kuznetsov–Benjamin-Bona-Mahony (ZK–BBM) equation
No full textAbstractIn this article, new (G′/G)-expansion method is used to look for the traveling wave solutions of nonlinear evolution equations and abundant traveling wave solutions to the Zakharov-Kuznetsov–Benjamin-Bona-Mahony equation are constructed. The performance of the method is reliable, useful and gives more new general exact solutions than the existing methods

Stability conditions on Kuznetsov components of Gushel-Mukai threefolds and Serre functor
Get PDFThis dissertation focuses on the construction of Serre-invariant Bridgeland stability conditions on Kuznetsov components of Gushel-Mukai threefolds. In particular, for a Gushel-Mukai threefold with Kuznetsov component and Serre functor , we find a family of stability conditions on such that for some residing in the universal cover of . This leads to an explicit construction of Bridgeland stability conditions on Kuznetsov components of special Gushel-Mukai fourfolds, which previously was not known
P.G. Kuznetsov and the Problem of Sustainable Development of Humanity in the Nature - Society - Man System
Get PDFThis book is devoted to the formation and development of scientific and engineering views on topical issues of sustainable development in the "nature - society - man" system. It is especially important in the context of the global systemic crisis, when the need for new scientific ideas and innovative engineering solutions is urgent.
The paper briefly provides the legacy of outstanding Russian scientist Pobisk G. Kuznetsov in the field of science and engineering for sustainable development. It shows the possibility of scientific solutions for extremely complex issues of sustainable development.
The book is intended for students, post-graduate students, young scientists and a wide range of specialists in scientific, technical and social areas, interested in the problem of designing and managing sustainable innovative development in the "nature - society - man" system.
