The article by Bilander Allahverdiyev, a professor of the Department of Mathematics, Khazar University, entitled "Dilation, Model, Scattering and Spectral Problems of Second-Order Matrix Difference Operator" was published in "Filomat" Journal. Note that the "Filomat" journal is indexed in Scopus and Web of Science databases.

In the article, the maximal dissipative singular matrix-difference operator of the second order, which is an extension of the minimal symmetric operator with maximal defect index defined in Hilbert space, is investigated.
