Injectivity versus surjectivity and Multipliers versus quotients in Matrices, Function algebras and operator algebras



We shall begin with  examples of classes of maps for which injectivity implies     surjectivity or surjectivity implies injectivity and give a gentle introduction to the notion of surjunctivity a la M. Gromov. Next, we will solve systems of equations via generalized   inverses. Then we will give definitions and a few properties of multipliers and quotient rings of algebras. We will illustrate them for algebras of functions or operators, particularly in the contexts of group algebras or semigroup  algebras or hypergroup algebras
