Remarks on time dependent periodic Navier-Stokes flows on a two-dimensional torus
No full textThis note is a continuation of the earlier paper [Chen, Z. M., Price, W. G.: Time dependent periodic Navier–Stokes flows on a two-dimensional torus. Commun. Math. Phys. {\bf 179}, 577–597 (1996)], where the evidences of the occurrence for the time dependent periodic Navier–Stokes flows were found based on a combination of analysis and computation. This investigation is now confirmed via rigorous analysis. The existence of the time dependent periodic Navier–Stokes flows on a two-dimensional torus is prove

Price hedonics: a critical review
No full textThis paper was presented at the conference "Economic Statistics: New Needs for the Twenty-First Century," cosponsored by the Federal Reserve Bank of New York, the Conference on Research in Income and Wealth, and the National Association for Business Economics, July 11, 2002. The main objective of this paper is to make a start in the evaluation of price hedonics. The author describes the hedonic model and reviews its main uses, because the credibility of price hedonics depends in part on the current state of academic research. This is a brief overview. The author then turns to some of the standard criticisms of price hedonics and moves into the uncharted waters of the political economy of price measurement.Statistics ; Prices ; Consumer price indexes
On the relation between Rayleigh-Bénard convection and Lorenz system
No full textBased on an extension of the Lorenz truncation scheme, a chaotic mathematical model is developed to provide a profile of the chaotic attractor associated with the Rayleigh–Bénard convection problem in a plane fluid motion. The attractor of the Lorenz system is a cross-section of the attractor of the proposed model, in which solutions always exist in circles mirroring those appearing in the convection problem
Decay estimates of linearized micropolar fluid flows in R3 spaces with applications to L3-strong solutions
No full textThrough analytical argument, the Lp ? Lq estimate of a three-dimensional linearized micropolar fluid flow in the whole space R3 is established. This estimate is used to show the existence and uniqueness of small L3-strong solutions of the micropolar fluid motion system. Sharp time decay estimates of the L3-strong solutions are derived
