Core and Core-EP Inverses of Tensors
Jajati Kesahri Sahoo, Ratikanta Behera, Predrag S. Stanimirovic +2
Specific definitions of the core and core-EP inverses of complex tensors are introduced. Some characterizations, representations and properties of the core and core-EP inverses are…
An improved method for the computation of the Moore-Penrose inverse matrix
Vasilios N. Katsikis, Dimitrios Pappas, Athanassios Petralias
In this article we provide a fast computational method in order to calculate the Moore-Penrose inverse of singular square matrices and of rectangular matrices. The proposed method…
Computation of vector sublattices and minimal lattice-subspaces of R^k. Applications in finance
V. N. Katsikis, I. A. Polyrakis
In this article we perform a computational study of Polyrakis algorithms presented in [12,13]. These algorithms are used for the determination of the vector sublattice and the mini…
