Kaniuth and Lau survey roughly 50 years of research into the role that Fourier and Fourier-Stieltjes algebras has played not only in helping clarify the natural of locally compact groups, but also in building bridges between abstract harmonic analysis,

Banach algebras, and operator algebras.

Banach algebras, to appear.

As a corollary of Theorem 5, we obtain the following stability result of (6), which generalizes stability result on

Banach algebras.

Dhage, "A fixed point theorem in

Banach algebras with applications to fractional integral equations," Kyungpook Mathematical Journal, vol.

The study gained momentum after the formulation of the hybrid fixed point principles in

Banach algebras due to Dhage [7, 8].

Let A and B be complex

Banach algebras and let [phi] : A [right arrow] B be a linear map.

Rota-Baxter operators appeared in the work of Baxter [3] on differential operators on commutative

Banach algebras, being particularly useful in relation to the Spitzer identity.

Banach algebras, Bull.

M-Ideals in Banach Spaces and

Banach Algebras. Lecture Notes in Mathematics, vol.

The main objective of the present study is to establish an existence result for the problem (1) under Lipschitz and Caratheodory conditions by applying a fixed point theorem in

Banach algebras due to Dhage [35].

By the middle of the summer of 1958 I finished writing my Diploma thesis: a theorem of decomposition of an anti-symmetric

Banach algebra into a direct sum of two symmetric

Banach algebras which Foias and myself proved.
