They study the space of almost convergent functions and obtain characterization theorems similar to known theorems about real functions. They also establish the existence of a unique invariant mean on vector-valued weakly almost periodic functions.spajournal articlehttp://www.collectanea.ub.edu/index.php/Collectanea/article/view/3441/4120http://www.collectanea.ub.edu/index.php/Collectanea/open access517.98Means on groupssemigroupsAnálisis funcional y teoría de operadores
