Anomalous Transport of Heterogeneous Population and Time-Changed Pólya Process
MathematicsWe propose a continuous-time unidirectional random walk model for a heterogeneous population of particles involving subdiffusive trapping effects. In this model, after escaping from the trap, each particle either jumps forward with a random probability ...
