Least-squares formulations for Stokes equations with non-standard boundary conditions -- A unified approach
Subhashree Mohapatra, N. Kishore Kumar, Shivangi Joshi
In this paper, we propose a unified non-conforming least-squares spectral element approach for solving Stokes equations with various non-standard boundary conditions. Existing leas…

Literature survey on low rank approximation of matrices
N. Kishore Kumar, Jan Shneider
Low rank approximation of matrices has been well studied in literature. Singular value decomposition, QR decomposition with column pivoting, rank revealing QR factorization (RRQR),…
