ON ALMOST AXISYMMETRIC INCOMPRESSIBLE MAGNETOHYDRODYNAMICS IN THREE DIMENSIONS
《Acta Mathematica Scientia》2025年第2期446-472,共27页Qunyi BIE Hao CHEN 
supported by the National Natural Science Foundation of China(11871305).
In this paper,we study the Cauchy problem of three-dimensional incompressible magnetohydrodynamics with almost symmetrical initial values in the cylindrical coordinates.Here the almost axisymmetric means that(■θu_(0...

Completion of the Proof of the Contradiction of Set Theory
《Advances in Pure Mathematics》2024年第11期807-816,共10页Yury M. Volin 
The article is devoted to completing the proof of the inconsistency of set theory. In this article and in the two preceding ones, all steps of the proof are based on generally accepted informal set-theoretic reasoning...
