Abstract
G. Fichera [1, 2, 3, 4, 5 and 6] has recently continued the theory of materials with memory or with heredity (in the following we shall indifferently use both these locutions). With deep analytic considerations he has thrown light on the difficulties which could arise in this theory, even in the hypotheses of “Fading Memory”. His results have given rise to a great deal of discussion.
