Normality and paranormality in product spaces

σ-Normality of Topological Spaces

Frames in 2-inner Product Spaces

In this paper, we introduce the notion of a frame in a 2- inner product space and give some characterizations. These frames can be considered as a usual frame in a Hilbert space, so they share many useful properties with frames.

Atomic Systems in 2-inner Product Spaces

In this paper, we introduce the concept of family of local atoms in a 2-inner product space and then this concept is generalized to an atomic system. Besides, a characterization of an atomic system lead to obtain a new frame. Actually this frame is a generalization of previous works.

σ-normality of topological spaces

Normality and non-normality of group compactifications in simple projective spaces

If G is a complex simply connected semisimple algebraic group and if λ is a dominant weight, we consider the compactification Xλ ⊂ P (
