| contents | We define a certain Hecke theoretic notion of family of smooth admissible representations of $GL_n(F)$, or of products of such groups, where $F$ is a nonarchimedean local field of characteristic zero. While this notion of family is rather weak a priori, we show that it implies strong rigidity properties for the Bernstein-Zelevinsky presentations of the members of such families, as well as for the variation of their epsilon factors (attached to arbitrary functorial lifts). Examples of such families come often from the theory of eigenvarieties, and in this case our results imply analyticity properties for the epsilon factors of the members of these families. |
