We consider the bilinear Fourier integral operatorS (f, g)(x) =ZRdZRdei 1(x, )ei 2(x, ) (x, , ) ˆ f( )ˆg( )d d ,on modulation spaces. Our aim is to indicate this operator is ...

The paper deal with non-commutative geometry. The notion of quantumspheres was introduced by podles. Here we define the quantum hermitianmetric on the quantum spaces and find it for the quantum spheres.

The purpose of this paper is to study and give the necessary andsufficient condition of strong convergence of the multi-step iterative algorithmwith errors for a finite family of generalized asymptotically ...

In this paper, we introduce the concept of generalized -contractivityof a pair of maps w.r.t. another pair. We establish a common fixed point result fortwo pairs of self-mappings, when one of these pairs is ...

We present some new results on the existence and the approximationof common fixed point of expansive mappings and semigroups in probabilisticmetric spaces.

The main goal of this note is to introduce another second-order differenceequation where every nontrivial solution is of minimal period 5, namelythe difference equation:xn+1 =1 + xn−1xnxn−1 − ...

In this paper, we reconstruct the Hardy-Littlewood's inequality byusing the method of the weight coefficient and the technic of real analysis includinga best constant factor. An open problem is raised.

In this paper, we provide a short account of the study of Hilbert-typeinequalities during the past almost 100 years by introducing multi-parametersand using the method of weight coefficients. A basic theorem ...
