Solved and unsolved problems in generalized notions of Connes amenability
A
Mahmoodi Kebriya
We survey the recent investigations on (bounded, sequential) approximate Connesamenability and pseudo-Connes amenability for dual Banach algebras. We will discuss thecore problems concerning these notions and address the signicance of any solutions to themto the development of the eld.

The extension of quadrupled xed point results in K-metric spaces
G
Soleimani Rad
Recently, Rahimi et al. [Comp. Appl. Math. 2013, In press] dened the conceptof quadrupled xed point in K-metric spaces and proved several quadrupled xed pointtheorems for solid cones on K-metric spaces. In this paper some quadrupled xed point resultsfor T-contraction on K-metric spaces without normality condition are proved. Obtainedresults extend and generalize well-known comparable results in the literature.

G-Frames, g-orthonormal bases and g-Riesz bases
S
S. Karimizad
G-Frames in Hilbert spaces are a redundant set of operators which yield a repre-sentation for each vector in the space. In this paper we investigate the connection betweeng-frames, g-orthonormal bases and g-Riesz bases. We show that a family of bounded opera-tors is a g-Bessel sequences if and only if the Gram matrix associated to its denes a boundedoperator.

Expansion of Bessel and g-Bessel sequences to dual frames and dual g-frames
M. S
Asgari
G
Kavian
In this paper we study the duality of Bessel and g-Bessel sequences in Hilbertspaces. We show that a Bessel sequence is an inner summand of a frame and the sum of anyBessel sequence with Bessel bound less than one with a Parseval frame is a frame. Next wedevelop this results to the g-frame situation.
