On time-fractional partial differential equations of time-dependent piecewise constant order
arxiv(2024)
摘要
This contribution considers the time-fractional subdiffusion with a
time-dependent variable-order fractional operator of order β(t). It is
assumed that β(t) is a piecewise constant function with a finite number
of jumps. A proof technique based on the Fourier method and results from
constant-order fractional subdiffusion equations has been designed. This novel
approach results in the well-posedness of the problem.
