in this paper, we introduce and study the notion of precompacttopological generalized groups and some new results are given.

given a mapping $f:xto x$ we naturally associate to it a monotonic map $gg_f:exp xto exp x$ from the power set of $x$ into itself, thus inducing a generalized topology on $x$. in this paper we investigate some properties of generalized topologies which are defined by such a procedure.

in this paper, using a generalized translation operator, we prove theestimates for the generalized fourier-bessel transform in the space l2 on certainclasses of functions.

let $a_1$, $a_2$ be unital banach algebras and $x$ be an $a_1$-$a_2$- module. applying the concept of module maps, (inner) modulegeneralized derivations and  generalized first cohomology groups, wepresent several results concerning the relations between modulegeneralized derivations from $a_i$ into the dual space $a^*_i$ (for$i=1,2$) and such derivations  from  the triangular banach algebraof t...

The research in this paper was motivated by one of the most important open problems in the theory of generalized polygons, namely the existence problem for semi-finite thick generalized polygons. We show here that no semi-finite generalized hexagon of order (2, t) can have a subhexagon H of order 2. Such a subhexagon is necessarily isomorphic to the split Cayley generalized hexagon H(2) or its ...

Identifying homogeneous subgroups of variables can be challenging in high dimensional data analysis with highly correlated predictors. The generalized fused lasso has been proposed to simultaneously select correlated variables and identify them as predictive clusters. In this article, we study several properties of generalized fused lasso. First, we present a geometric interpretation of the gen...

This paper begins with a complete description of the complex Poynting theorem, followed by a rigorous study of the generalized resonance in a multi-antenna system. The condition generating the generalized resonance is discussed, which is the balance of the electromagnetic fields energy stored in the antennas open system. The matrix expression of the generalized resonant factor (GRF ) is derived...

backgroundcongenital generalized lipodystrophy (cgl) is a rare disease. it is associated with near total fat loss, severe insulin resistance and hypoleptinemia leading to metabolic derangements.case presentationwe report a 25- year- old female with 1-acylglycerol-3-phosphate-o-acyltransferase 2 (apgat2) mutation, and both sclerotic and lytic bone lesions together for the first time. bone cyst i...
