3. Algebraic properties of Mehler–Fock convolution and applications.

Author

Van Hoang, Pham, Thanh Hong, Nguyen, Huy, Le Xuan, and Hong Van, Nguyen

Subjects
*INTEGRO-differential equations, *INTEGRAL equations, *MATHEMATICAL convolutions, *FREDHOLM equations, *BANACH algebras
Abstract

In this paper, we study some properties of the Mehler–Fock convolution operator. We also analyse the Banach algebraic structure on the space of integrable functions $ L_1(1,\infty) $ L 1 (1 , ∞) with the multiplication being the Mehler–Fock convolution. The Titchmarsh-type theorem for this convolution operator is also obtained. As applications, we apply these properties of the convolution operator to solve some classes of Fredholm integral and integro-differential equations and prove some priori estimations under the given conditions.

11. Asymptotics of the scattered Debye potentials via a generalized convolution.

Author

Thao, Nguyen Xuan, Tuan, Vu Kim, Van Hoang, Pham, and Hong, Nguyen Thanh

Subjects
ASYMPTOTES, ANALYTIC geometry, MATHEMATICAL functions, MATHEMATICS, INTEGRALS
Abstract

In this paper, we express the scattered Debye potentials via a new generalized convolution related to the Kontorovich-Lebedev integral. The uniform asymptotics of the scattered Debye potentials under very mild conditions on spectral functions are obtained, and an inverse problem of finding spectral functions from given Debye potentials is considered.
