- We study the existence of positive eigenpairs for a class of Caputo fractional autonomous evolution equations with nonlocal initial condition within the framework of Banach lattices. The autonomous linear operator generates a compact strongly continuous semigroup of contractions, while the nonlinearity is a Caratheodory map. The mild eigenfunction is represented via the compact Mittag--Leffler operator families, we work within a positive cone of continuous functions and establish a uniform lower bound for the solution operator on the boundary. We apply the Birkhoff--Kellogg type theorem in cone for the existence of eigenpair. Our approach requires neither Lipschitz continuity of the nonlinearity nor the compactness of nonlocal initial operator, allowing for broad applicability to periodic, multi-point, and integral-type initial conditions. The theoretical results are applied to a parabolic fractional partial differential equation.
