heal.abstract	LetP(?) be ann×n analytic matrix function andW(P) be its numerical range. In this paper classical results on the normality of matrix eigenvalues on ?W(P) are generalized to the context of such matrix functions. Special attention is paid to corners of ?W(P) and to the special case of matrix polynomialsP(?).	en
