Given the present status of English as the language for international business and scientific and technical communication, more and more specialised courses are being demanded by students or professionals from different fields, ranging from medicine and...

Artículos Aizpuru: mber that a closed subspace M of a real Banach space X is said to be an L2- summand subspace if there exists another closed subspace N of X verifying X = (M ® N)2 (that is, ¡m + n||2 = ||m||2 + ||n||2 for every m e M and every n g N.) The linear projection t?m of X onto M that fixes the elements of M and maps the elements of N to {0} is called the L2-summand projection of X onto M. For a wider perspective about L2-summand subspaces,...
