Abstract: We study a fractional parabolic problem with a variable exponent and an integrable source term. Our goal is to establish the existence and uniqueness of a renormalized solution. The functional setting involves Lebesgue and Sobolev spaces with variable exponent. Some a-priori estimates are used to obtain our results.
Keywords: fractional $p({\cdot})$-Laplacian; parabolic problem; existence and uniqueness of renormalized solution; variable exponent
