Upper and lower alpha (mu_{X};mu_{ Y} )-continuous multifunctions
M
Akdag
F
Erol
In this paper, a new class of multifunctions, called generalized alpha (mu_{X};mu_{ Y} )-continuous multifunctions, has been dened and studied. Some characterizations and severalproperties concerning generalized alpha (mu_{X};mu_{ Y} )-continuous multifunctions are obtained. The re-lationships between generalized alpha (mu_{X};mu_{ Y} )-continuous multifunctions and some known con-cepts are also discussed.

Characterization of G2(q), where 2 < q = 1(mod3) by order components
P
. Nosratpour
In this paper we will prove that the simple group G2(q) where 2 < q = 1(mod3)is recognizable by the set of its order components, also other word we prove that if G is anite group with OC(G) = OC(G2(q)), then G is isomorphic to G2(q).

Frames for compressed sensing using coherence

We give some new results on sparse signal recovery in the presence of noise, forweighted spaces. Traditionally, were used dictionaries that have the norm equal to 1, but, forrandom dictionaries this condition is rarely satised. Moreover, we give better estimationsthen the ones given recently by Cai, Wang and Xu.

Hassani
In this paper, we state some results on product of operators with closed rangesand we solve the operator equation TXS*- SX*T*= A in the general setting of theadjointable operators between Hilbert C*-modules, when TS = 1. Furthermore, by usingsome block operator matrix techniques, we nd explicit solution of the operator equationTXS*- SX*T*= A.

Numerical solution of Fredholm integral-dierential equations on unbounded domain
M

A
Riahifar
In this study, a new and ecient approach is presented for numerical solution ofFredholm integro-dierential equations (FIDEs) of the second kind on unbounded domainwith degenerate kernel based on operational matrices with respect to generalized Laguerrepolynomials(GLPs). Properties of these polynomials and operational matrices of integration,dierentiation are introduced and are ultilized to reduce the (FIDEs) to the solution ofa system of linear algebraic equations with unknown generalized Laguerre coecients. Inaddition, two examples are given to demonstrate the validity, eciency and applicability ofthe technique.

On duality of modular G-Riesz bases and G-Riesz bases in Hilbert C*-modules
M
Rashidi-Kouchi
In this paper, we investigate duality of modular g-Riesz bases and g-Riesz basesin Hilbert C*-modules. First we give some characterization of g-Riesz bases in Hilbert C*-modules, by using properties of operator theory. Next, we characterize the duals of a giveng-Riesz basis in Hilbert C*-module. In addition, we obtain sucient and necessary conditionfor a dual of a g-Riesz basis to be again a g-Riesz basis. We nd a situation for a g-Rieszbasis to have unique dual g-Riesz basis. Also, we show that every modular g-Riesz basis is ag-Riesz basis in Hilbert C*-module but the opposite implication is not true.

Here, a new certain class of contractive mappings in the bmetric spaces is intro-duced. Some xed point theorems are proved which generalize and modify the recent resultsin the literature. As an application, some results in the bmetric spaces endowed with apartial ordered are proved.
