Some results involving the Aα-eigenvalues for graphs and line graphs
Special MatricesLet GG be a simple graph with adjacency matrix A(G)A\left(G), degree diagonal matrix D(G),D\left(G), and let l(G)l\left(G) be the line graph of GG. In 2017, Nikiforov defined the Aα{A}_{\alpha }-matrix of GG, Aα(G){A}_{\alpha }\left(G), as a linear ...

Едно неравенство за обобщени хроматични графи
, 2012 Асен Божилов, Недялко Ненов - Нека G е n-върхов граф и редицата от степените на върховете му е d1, d2, . . . , dn, а V(G) е множеството от върховете на G. Степента на върха v бележим с d(v). Най-малкото естествено число r, за което V(G) има r-разлагане V(

On the fractional dimension of partially ordered sets
, 1994 We use a variety of combinatorial techniques to prove several theorems concerning fractional dimension of partially ordered sets. In particular we settle a conjecture of Brightwell and Scheinerman by showing that the fractional dimension of a poset is ...
