✦ Synopsis
A product integral solution of the abstract evolution equation u'(t) = Hi(t) u(t) is obtained in the event that H~(t) belongs to a class of generahzed operator-valued functions involving singular perturbations in the interaction representation (H1(t) = ie -imo Ve,No, where Ho is a power of ( -d )1/2 in L 2 (R"), and V is a suitable distribution).

## Abstract This paper is devoted to the study on the __L^p^__ ‐mapping properties for certain singular integral operators with rough kernels and related Littlewood–Paley functions along “polynomial curves” on product spaces ℝ^__m__^ × ℝ^__n__^ (__m__ ≥ 2, __n__ ≥ 2). By means of the method of bl
Using the methods of differential subordination and superordination, sufficient conditions on the integral operator of meromorphic functions in the punctured unit disk for obtaining, respectively, the best dominant and the best subordinant are determined. New Sandwichtype results are also obtained.
In this paper, based on Wu's generalized fuzzy integrals of point-valued function [C. Wu et al., Fuzzy Sets and Systems 70 (1995) 75], a theory of generalized fuzzy integrals of fuzzy-valued functions will be investigated. It includes definitions, properties and various kinds of convergence theorems
In this paper we investigate a class of p-valent analytic functions with ÿxed argument of coe cient, which is deÿned in terms of certain di erential-integral operators. Coe cient estimates, distortion theorems, extreme points, the radii of convexity and starlikeness in this class are given.
