Journal ArticleDOI
Young-type inequalities and their matrix analogues
TL;DR: In this article, the Young-type inequalities for positive real numbers and their matrix analogues for positive definite matrices were presented and compared to the matrix analogue of the double-inequality.
Journal ArticleDOI
On structural properties of trees with minimal atom-bond connectivity index III
TL;DR: In this article, it was shown that minimal-ABC trees of order larger than 168 and with a pendent path of length 3 do not contain B2-branches, while trees with minimal ABC index with a path length of 3 do contain Bk-branch.
Journal ArticleDOI
Some comments on k-tridiagonal matrices
TL;DR: The aim of this comment is to provide a general, unified, and attractive approach to the determinant, the spectrum, and the inverse of the so-called k-tridiagonal matrices.
Journal ArticleDOI
On a family of trees with minimal atom-bond connectivity index
Zhibin Du,Carlos M. da Fonseca +1 more
TL;DR: Some structural properties of one family of trees containing a pendent path of length 3 which would minimize the ABC index are presented, mainly including: it contains no the so-called B k with k ?
Journal ArticleDOI
Basic trigonometric power sums with applications
TL;DR: In this article, the authors presented the transformation of several sums of positive integer powers of the sine and cosine into non-trigonometric combinatorial forms, and applied the results to the derivation of generating functions and to the number of closed walks on a path and in a cycle.
