摘要

This paper considers traces at the initial time for solutions of evolution equations with local or non-local derivatives in vector-valued \(L_p\) L p spaces with \(A_p\) A p weights. To achieve this, we begin by introducing a generalized real interpolation method. Within the framework of generalized interpolation theory, we make use of stochastic process theory and two-weight Hardy’s inequality to derive our trace and extension theorems. Our results encompass findings applicable to time-fractional equations with broad temporal weight functions.
