Representation of Zeros of a Copositive Matrix via Maximal Cliques of a Graph
O. I. Kostyukova, T. V. Tchemisova
There is a profound connection between copositive matrices and graph theory. Copositive matrices provide a powerful tool for formulating and solving various challenging graph-relat…
Face reduction and the immobile indices approaches to regularization of linear Copositive Programming problems
Olga Kostyukova, Tatiana Tchemisova
The paper is devoted to the regularization of linear Copositive Programming problems which consists of transforming a problem to an equivalent form, where the Slater condition is s…
Strong duality for a problem of linear copositive programming
Olga Kostyukova, Tatiana Tchemisova
The paper is dedicated to the study of strong duality for a problem of linear copositive programming. Based on the recently introduced concept of the set of normalized immobile ind…
Spinning rough disk moving in a rarefied medium
Alexander Plakhov, Tatiana Tchemisova
A spinning rough disk moves through a rarefied medium on the plane. The roughness is formed by small cavities on the disk boundary. The medium is so rare that mutual interaction of…
