TY - JOUR AU - Kostić, Marko PY - 2017 TI - On Almost Periodic Solutions of Abstract Semilinear Fractional Inclusions with Weyl-Liouville Derivatives of Order γ ∈ (0, 1] JF - Journal of Mathematics and Statistics VL - 13 IS - 3 DO - 10.3844/jmssp.2017.240.250 UR - https://thescipub.com/abstract/jmssp.2017.240.250 AB - The main aim of this paper is to examine the existence and uniqueness of almost periodic solutions for a class of (semilinear) fractional relaxation inclusions with Stepanov almost periodic coefficients. We deal with the Weyl-Liouville fractional derivatives of order γ ∈ (0, 1], paying special attention to the analysis of semilinear differential inclusions of first order. We use the results from the theory of fractional powers of sectorial multivalued linear operators to achieve our goals, providing an interesting application to semilinear fractional Poisson heat equation in Lp-spaces.
