[ 1 ] - A Note on Quadratic Maps for Hilbert Space Operators

In this paper, we introduce the notion of sesquilinear map on Β(H) . Based on this notion, we define the quadratic map, which is the generalization of positive linear map. With the help of this concept, we prove several well-known equality and inequality...

[ 2 ] - Parametric Technology Display and Matemhtical Model Of Technology Spillover

In this paper, parametric technology display and a mathematical model of technology spillover as a different approach based on the technology changes would be discussed. The recently action that will be accomplished through formation matrices of technological changes, measure of technology spillover and other concepts along with a variety of matrices types. Several examples are given and the re...
