In this paper, we determine the normal forms of idempotent matrices for similarity over finite local rings Z/pkZ, from which we construct a Cartesian authentica
Let G = (V, E) be a primitive digraph. The vertex exponent of G at a vertex v ∈ V, denoted by expG(v), is the least integer p such that there is a v → u walk
In this paper, by the method of upper and lower solutions, we establish the existence of the non-trivial nonnegative periodic solutions for a class of degenerat
In this paper, we prove the existence in H2+, an incomplete metric subspace of H2×H2×H2, of global solutions to the system for a one-dimensional non-monotone
In the paper we obtain vector-valued inequalities for Calderon-Zygmund operator,simply CZO On Herz space and weak Herz space.In particular,we obtain vector-valu
