Numerical range for weighted Moore-Penrose inverse of tensor
Aaisha Be, Vaibhav Shekhar, Debasisha Mishra
This article first introduces the notion of weighted singular value decomposition (WSVD) of a tensor via the Einstein product. The WSVD is then used to compute the weighted Moore-P…
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…
Three-step alternating iterations for index one matrices
Ashish Kumar Nandi, Jajati Keshari Sahoo, Debasisha Mishra
Iterative methods based on matrix splittings are useful in solving large sparse linear systems. In this direction, proper splittings and its several extensions are used to deal wit…
Comparison results for proper multisplittings of rectangular matrices
Chinmay Kumar Giri, Debasisha Mishra
The least square solution of minimum norm of a rectangular linear system of equations can be found out iteratively by using matrix splittings. However, the convergence of such an i…
Proper Weak Regular Splitting and its Application to Convergence of Alternating Iterations
Debasisha Mishra
The theory of matrix splitting is a useful tool for finding solution of rectangular linear system of equations, iteratively. The purpose of this paper is two-fold. Firstly, we revi…
