Convergence of two-stage iterative scheme for -weak regular splittings of type II with application to Covid-19 pandemic model

Vaibhav Shekhar, Nachiketa Mishra, Debasisha Mishra

Monotone matrices play a key role in the convergence theory of regular splittings and different types of weak regular splittings. If monotonicity fails, then it is difficult to gua…

Alternating Stationary Iterative Methods Based on Double Splittings

Ashish Kumar Nandi, Nachiketa Mishra, Debasisha Mishra

Matrix double splitting iterations are simple in implementation while solving real non-singular (rectangular) linear systems. In this paper, we present two Alternating Double Split…

The Exponentially Faster Stick-Slip Dynamics of the Peeling of an Adhesive Tape

Nachiketa Mishra, Nigam Chandra Parida, Soumyendu Raha

The stick-slip dynamics is considered from the nonlinear differential-algebraic equation (DAE) point of view and the peeling dynamics is shown to be a switching differential index…
