Generalized Frames for B(H, K)
Frames play significant role in various areas of science and engineering. Motivated by the work of Chander Shekhar, S. K. Kaushik and Abas Askarizadeh, Mohammad Ali Dehghan, we introduce the concepts of $K$-frames for $B(mathcal{H, K})$ and we establish some result. Also, we consider the relationships between $K$-Frames and $K$-Operator Frames for $B(mathcal{H})$.
متن کاملPREPARATION AND CHARACTERIZATION OF [Ni (MAP) ] ; H- MAP = 2- (METHYLAMINO) PYRIDINE H. Aghabozorg* and H. H. Monfared
We have recently synthesized [Ni (MAP) ] complex [H-MAP= 2- (methylamino) pyridine]. 2- (Methy1amino)pyridine reacts with MeLi in THF and generates the lithium salt (Li-MAP). Further reaction of NiCl with two equivalent of this ligand in THF leads to the formation of a dark red solution. Analytical data, molecular weight, and magnetic susceptibility of this complex confirm the formula [N...

متن کاملH-triangles with k interior H-points
An H -triangle is a triangle with corners in the set of vertices of a tiling of R2 by regular hexagons of unit edge. It is known that any H -triangle with exactly 1 interior H -point can have at most 10 H -points on its boundary. In this note we prove that any H -triangle with exactly k interior H -points can have at most 3k+7 boundary H -points. Moreover we form two conjectures dealing with H ...
