| contents | In this paper we examine boundary effects in a fractional chemotactic equation derived from a kinetic transport model describing cell movement in response to chemical gradients (chemotaxis). Specifically, we analyze reflecting boundary conditions within a nonlocal fractional framework. Using boundary layer methods and perturbation theory, we derive first-order approximations for interior and boundary layer solutions under symmetric reflection conditions. This work provides fundamental insights into the complex interplay between fractional dynamics, chemotactic transport phenomena, and boundary interactions, opening future research in biological and physical applications involving nonlocal processes. |
