In recent years there has been much interest in the existence of positive solutions of nonlinear boundary value problems, with a positive nonlinearity f, where the boundary

T. In this paper we consider one-dimensional two-phase Stefan problems for a class of parabolic equations with nonlinear heat source terms and with nonlinear flux conditions on the

In Section 7 two-sided estimates of the mixed moduli of smoothness in terms of the Fourier coefficients are given. It is well known that these results are closely connected to

It is suggested by our method that most of the quadratic algebras for all St¨ ackel equivalence classes of 3D second order quantum superintegrable systems on conformally flat

A monotone iteration scheme for traveling waves based on ordered upper and lower solutions is derived for a class of nonlocal dispersal system with delay.. Such system can be used

There are many exciting results concerned with the exis- tence of positive solutions of boundary-value problems of second or higher order differential equations with or
