Abstract In this paper we consider the operator D λ α f in terms of the generalized S˘al˘agean and Ruschweyh operators, and we study several differ- ential subordinations generated by
But a problem of the Darboux type with boundary conditions of form (6) on temporal hyperplanes is uniquely solvable for one hyperbolic equation of second-order with

For instance, the delay equation does not inherit the classical properties of the Dirichlet boundary value prob- lem for the heat equation: the maximum principle is not valid,
The Fuˇc´ık spectra have been investigated for the second order equation with different two-point boundary conditions.. This paper is organized
The situation in the present case is complicated by the fact that there is an inner point in the boundary conditions, in contrast to the ”standard” boundary conditions as the
