Special Issue Information

Dear Colleagues,

Fractional differential equations are being applied in medicine (modelling of human tissue under mechanical loads), (bio-)chemistry (modelling of polymers and proteins), mechanics (theory of viscoelasticity), electrical engineering (transmission of ultrasound waves), etc.

The aim of this Special Issue is to present some of the recent developments in the theory, methods, and applications of certain particularly important special cases which will demonstrate a rich variety of phenomena that may be encountered in the investigation of regular and singular fractional differential equations. This includes an analysis of solutions of regular fractional differential equations where the main emphasis will be on initial and boundary value problems, existence and uniqueness questions, the structural stability of the solutions, the smoothness properties of the solutions. However, singular equations will lead to solutions with properties that differ substantially from those that we have seen for regular problems.

The key objective of this Special Issue is to provide novel developments that may inspire advances or be used for the construction of numerical methods for fractional differential equations.

This paper deals with a singular two dimensional initial boundary value problem for a Caputo time fractional parabolic equation supplemented by Neumann and non-local boundary conditions. The well posedness of the posed problem is demonstrated in a fractional weighted Sobolev space. The used method based on some functional analysis tools has been successfully showed its efficiency in proving the existence, uniqueness and continuous dependence of the solution upon the given data of the considered problem. More precisely, for proving the uniqueness of the solution of the posed problem, we established an energy inequality for the solution from which we deduce the uniqueness. For the existence, we proved that the range of the operator generated by the considered problem is dense. Full article
