We present a kind of solutions of D-equations in terms of what we have called a D-pair in this paper. Some properties of dimodules associated with D-pairs are d
We study a chemostat system with two parameters, S0-initial density and D-flow-speed of the solution. At first, a generalization of the traditional Hopf bifurca
Let LSC(X) denote the set of all proper lower semicontinuous functions on X with the epi-topology. In this paper we give characterizations of the separation axi
