Foundations for L-fractional partial differential equations
Develop rigorous theorems for L-fractional partial differential equations analogous to Caputo-based results, including existence, uniqueness, and representation via bivariate fractional power series.

Finally, what about fractional partial differential equations? There are no studies for the L-fractional derivative. In the Caputo context, formal solutions have been found in terms of bivariate fractional power series, but rigorous theorems are yet to be investigated.
