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…
On root-ratio multipoint methods for finding multiple zeros of univariate functions
Miodrag S. Petkovic, Ljiljana D. Petkovic
Several root-ratio multipoint methods for finding multiple zeros of univariate functions were recently presented. The characteristic of these methods is that they deal with -th…
A note on non-inclusion "interval" root solvers
Miodrag S. Petković, Ljiljana D. Petković
In this note we give comments on recent interval extensions of the King-Ostrowski multipoint methods for solving nonlinear equations published in at least five scientific journals…
A note on a new cubically convergent one-parameter root solver
L. D. Petković, M. S. Petković
A new one-parameter family of iterative method for solving nonlinear equations is constructed and studied. Two variants, both with cubic convergence, are developed, one for finding…
Iterative methods for the inclusion of the inverse matrix
Marko D. Petkovic, Miodrag S. Petkovic
In this paper we present an efficient iterative method of order six for the inclusion of the inverse of a given regular matrix. To provide the upper error bound of the outer matrix…
A Comparison between Different Concepts of Almost Orthogonal Polynomials
Predrag Rajkovic, Sladjana Marinkovic
In this paper, we will discuss the notion of almost orthogonality in a functional sequence.Especially, we will define a few sequences of almost orthogonal polynomials which can be…
