Maps on matrices that preserve the spectral radius distance

, 1999
Let ø be a surjective map on the space of n x n complex matrices such that r(ø(A)-ø(B))=r(A-B) for all A,B, where r(X) is the spectral radius of X.

A distance spectral radius for star-factors with large components in graphs

Let G be a graph and let m be an integer with m ≥ 2. A {K1,j : m ≤ j ≤ 2m}-factor of a graph G is a spanning subgraph of G, in which every component is isomorphic to an element in {K1,j : m ≤ j ≤ 2m}.

The distance spectral radius of $k$-uniform hypertrees with given number of vertices of maximum degree

This paper investigates the influence of two graft transformations on the distance spectral radius of connected uniform hypergraphs. Specifically, we study $k$-uniform hypertrees with given size, maximum degree and number of vertices of maximum degree ...
