Abstract: In this talk, I will discuss several notions that are extensions of the principal eigenvalue of a linear elliptic operator to the framework of unbounded domains. Some of the properties that one can derive for these generalized eigenvalues will be presented. I will describe as well applications to semi-linear elliptic equations and to propagation in reaction – diffusion equations of the KPP type. These equations are considered in unbounded domains and for general heterogeneous settings. Such problems arise for instance in population ecology. I report here on joint works with Luca Rossi, Francois Hamel and with Gregoire Nadin
