The regularity of random attractors is considered for the nonautonomous fractional stochastic FitzHugh-Nagumo system.We prove that the system has a pullback ran
Let S(m,d,k) be the set of k-uniform supertrees with m edges and diameter d,and S1(m,d,k) be the k-uniform supertree obtained from a loose path u1,e1,u2,e2,…,u
Let k ≥ 2 be an integer and P be a 2n × 2n symplectic orthogonal matrix satisfying Pk =I2n and ker(Pj-I2n) =0,1 ≤ j < k.For any compact convex hypersurface ∑
We prove that a Finsler manifold with vanishing Berwald scalar curvature has zero E-curvature.As a consequence,Landsberg manifolds with vanishing Berwald scalar
