Microsoft Excel is a versatile software program that allows you to create a variety of documents, images and charts. Create a linear scale in Excel to display the measurements of a map, drawing or ...

Algebraic structures and linear maps form a cornerstone in modern mathematics, underpinning areas as diverse as abstract algebra and functional analysis. Algebraic structures such as groups, rings, ...

For Banach spaces X and Y, we show that every unital bijective invertibility preserving linear map between L(X) and L(Y) is a Jordan isomorphism. The same conclusion holds for maps between CI + K(X) ...

In the first part we show that the decomposition of a bounded selfadjoint linear map from a $C^\ast$-algebra into a given von Neumann algebra as a difference of two ...
