We discuss some existence criteria for a new category of the Caputo conformable differential inclusion furnished with four-point mixed Riemann-Liouville conformable integro-derivative boundary conditions. In this way, we employ some analytical techniques on α-ψ-contractive mappings and operators having the approximate endpoint property to reach desired theoretical results. Finally, we provide an example to illustrate our last main result. MSC: Primary 34A08; secondary 34A12 Keywords:

For this reason, by increasing its knowledge, the mankind invoked new logical and computational tools. The mathematical operators are one of these useful tools for modeling natural processes in the world. Over the years, mathematicians have introduced various operators for different models, but since fractional order modelings are more accurate than integer order ones, new fractional operators have been defined for this purpose today. In the meantime, the Caputo and the Riemann-Liouville fractional operators have been used more than other operators for complicated fractional modelings (see, for example, [1] [2] [3] [4] [5] ). Lately, the Hadamard and Caputo-Hadamard fractional operators have been introduced by some researchers and then different modelings have been studied using these operators (see, for instance, [6] [7] [8] [9] ). In 2015, Caputo and Fabrizio [10] presented a new fractional derivative without singular kernel entitled fractional Caputo-Fabrizio operator, and in the same year, Losada and Nieto [11] investigated some properties of this new fractional operator. Some flexible properties of this nonsingular operator led to numerous papers on the various fractional modelings in this regard (see, for example, [12] [13] [14] ). Following this path, Abdeljawad [15] developed the concepts introduced in [16] and investigated some properties of the well-behaved conformable fractional derivatives. In a © The Author(s) 2020.
