Making use of certain operators of fractional calculus, we introduce a new class F-delta(n,lambda,alpha) of functions which are analytic in the open unit disk mu and obtain a necessary and sufficient condition for a function ...

Two subclasses A(alpha, beta) and R(p) of certain analytic functions in the open unit disk U are introduced. For these classes a majorization problem and a quasi-subordination problem of analytic functions in U are discussed.

We prove that a ring R is serial if and only if every finitely presented right and left R-module is circle plus-supplemented, and that R is artinian serial if and only if every right and left R-module is circle plus-supplemented. ...

Sufficient conditions for global nonexistence (blow up) of solutions of the initial-boundary value problem for a class of second-order quasilinear parabolic equations: [GRAPHICS] are established. (C) 1999 Elsevier Science ...

A certain subclass T(n,p,lambda,alpha) of starlike functions in the unit disk is introduced. The object of the present paper is to derive several interesting properties of functions belonging to the class T(n,p,lambda,alpha). ...

Let R be a commutative one-dimensional reduced local Noetherian ring whose integral closure (R) over tilde (in its total quotient ring) is a finitely generated R-module. We settle the last remaining unkown case of the ...

In this paper the authors lay the foundation for a theory of dicovers of ditopological texture spaces and use this to define notions of paracompactness and full normality. Some applications to fuzzy topology are also ...

In this paper it is shown that the lattice of intuitionistic subsets of a set X in the sense of D. Coker may be represented as a special type of texture space, called an intuitionistic texture on X, and various characterizations ...
