  The non-Markovian depolarizing channel is explored from the perspective of
understanding its non-Markovian behaviour as well as the occurrence of
singularities. The study brings together the various ways to identify and
quantify non-Markovianity. This includes dynamical techniques such as quantum
information backflow witness, BLP, RHP and HCLA measures. In addition,
geometrical visualization of non-Markovian effects is presented using the
variation in the volume of accessible states during dynamical evolution.
Further, a trajectory-based visualization of the dynamical map, of the
depolarizing channel, within the parameter space is presented. The trajectories
traced during evolution, demonstrate the loss of CP-divisibility and the
emergence of non-Markovianity under systematic variations of the system
parameters.
