The extremal solution to conformable fractional differential equations involving integral boundary condition

This thesis study consists of five parts. The first chapter is devoted to the introduction and a general literature information is given. In the second chapter, necessary basic definitions and concepts are given. In the third chapter, the existence of extreme solutions by using monotone iteration technique of fractional differential equations called conformable fractional differential equations is examined. In the fourth chapter, positive solutions of conformable fractional differential equations including Riemann-Stieltjes integral boundary conditions are studied. In the fifth chapter, discussion and conclusion are included.
