Caputo derivatives of fractional variable order: numerical approximations

Dina Tavares, Ricardo Almeida, Delfim F. M. Torres

We present a new numerical tool to solve partial differential equations involving Caputo derivatives of fractional variable order. Three Caputo-type fractional operators are consid…
