High Order Moment Closure with Global Hyperbolicity of Vlasov-Maxwell Equations
Moment closure Vlasov-Maxwell equation Boltzmann equation Ex-tended magnetohydrodynamics
2014/9/26
In this paper, we derive the extended magnetohydrodynamic models based on the
moment closure of the Vlasov-Maxwell equation. We adopt the Grad type moment
expansion which was firstly proposed in [12...

Nonlinear Dirac equation Solitary wave
2014/9/26
This paper concentrates on a (1+1)-dimensional nonlinear Dirac (NLD) equa-tion with a general self-interaction, being a linear combination of the scalar,
pseudoscalar, vector and axial vector self-in...
要证n>2时，A^n+B^n=C^n没有非零有理数解，可以等效地证明n=4和n为所有奇素数时A^n+B^n=C^n没有两两互质的正整数解即可。设A^4+B^4=C^4有两两互质的正整数解(a,b,c)，则a、b中必有一个为偶数且可建立递缩关系，最后导出1是偶数的矛盾，从而论证了A^4+B^4=C^4没有两两互质的正整数解；设n为某一奇素数时A^n+B^n=C^n有两两互质的正整数解(a,b,c)，...
The distributive law of primes in the natural numbers Even numbers 2x≥6 can be expressed as the sum of two primes
Goldbach hypothesis prime infimum
