We consider exceptional sets in the Waring-Goldbach problem for fifth powers.For example,we prove that all but O(N131/132) integers satisfying the necessary loc
We construct the Grothendieck rings of a class of 2n2 dimensional semisimple Hopf Algebras H2n2,which can be viewed as a generalization of the 8 dimensional Kac
The regularity of random attractors is considered for the nonautonomous fractional stochastic FitzHugh-Nagumo system.We prove that the system has a pullback ran
