Some bounds on the maximum induced matching numbers of certain grids
Deborah Olayide Ajayi, Tayo Charles Adefokun
An induced matching in a graph is a matching in that is also the edge set of an induced subgraph of . That is, any edge not in must have no more than one inciden…
Labeling of Direct Product of Cycles
Tayo Charles Adefokun, Deborah Olayide Ajayi
An -labeling of a graph is an assignment of labels from to the vertices of such that two vertices that are adjacent or have a common neighbor r…
Infinite Hankel Block Matrices, Extremal Problems
Lev Sakhnovich
In this paper we use the matrix analogue of eigenvalue to formulate and to solve the extremal Nehary problem. When is a scalar, our approach coincides with…
On the solutions of Knizhnik-Zamolodchikov system
Lev Sakhnovich
We consider the Knizhnik-Zamolodchikov system of linear differential equations. The coefficients of this system are rational functions. We prove that under some conditions the solu…
New XMM-Newton observations of SNRs in the SMC
M. D. Filipovic, F. Haberl, P. F. Winkler +6
A complete overview of the supernova remnant (SNR) population is required to investigate their evolution and interaction with the surrounding interstellar medium in the Small Magel…
Explicit Rational Solutions of Knizhnik-Zamolodchikov Equation
Lev Sakhnovich
We consider the Knizhnik-Zamolodchikov system of linear differential equations. The coefficients of this system are rational functions generated by elements of the symmetric group…
