Boundary value problems with four orders of Riemann-Liouville fractional derivatives
Boundary value problems with four orders of Riemann-Liouville fractional derivatives
In this paper we study a new class of boundary value problems for fractional differential equations which contains Riemann-Liouville fractional derivatives of four orders, two in a fractional differential equation and two in boundary conditions. Our results are based on some classical fixed point theorems. Some illustrative examples are also …
