Abstract: Using the fixed point theorems of increasing operator and the fixed point theorem of cone expansion and cone compression, we studied the positive solutions of a class of  multi-order fractional differential equations, and obtained the existence of positive solutions of the equations.

Key words: nonlinear system, Caputo fractional derivative, fixed point theorem, positive solution
