This paper considers diffusion processes {X^∈(t)} on R^2, which are pertur-bations of dynamical system {X(t)} (dX(t) = b(X(t))dt) on R^2. By means of weakconve
This paper proves that if the energy density of a harmonic map to a unit spherevaries between two successive half eigenvalues, then it must be one of them. Appl
A set of easily verifiable sufficient conditions are derived for the existence of positive periodic solutions for delayed generalized predator-prey dispersion s
This paper is a contionuation of [1] and is concerned with multiplication of weak functions. Here the weak functions are treated as generalized expansions in He
