Abstract
The aim of this research was to relate two physical effects for
partial differential equations on the time-coordinate, notably the multipledelay
times and fractional-derivative. Time Fractional Delay Partial Differential
Equations (TFDPDEs) usually interpret some complex physical
phenomenon. This study works to solve TFDPDE with shrinking in x and
proportional delays in t numerically by utilizing the fractional derivative
of Caputo sense in the numerical method known as Perturbation Iteration
Algorithm (PIA). A few famous numerical examples have been solved
using PIA and their comparison with an exact solutions is illustrated for
® = 1. Also, different values of ® have been depicted in graphical form to
show their fractional behavior. The delay term k is also discussed extensively
in this TFDPDE study. Numerical results show that this technique is
reliable, convenient, and attractive for computational use in modern times.
