ON THE SIZE, SPECTRAL RADIUS, DISTANCE SPECTRAL RADIUS AND FRACTIONAL MATCHINGS IN GRAPHS

Bulletin of the Australian Mathematical Society, 2023
AbstractWe first establish a lower bound on the size and spectral radius of a graph G to guarantee that G contains a fractional perfect matching. Then, we determine an upper bound on the distance spectral radius of a graph G to ensure that G has a fractional perfect matching.

Local Spectral Radius Preservers

Integral Equations and Operator Theory, 2013
Let \(X\) be an infinite-dimensional complex Banach space and \(\mathcal B(X)\) the space of all bounded operators on \(X\). The authors show that, if \(\varphi\) is a surjective map on \(\mathcal B(X)\) such that \(\mathrm r_{T-S}(x)=0\) if and only if \(\mathrm r_{\varphi(T)-\varphi(S)}(x)=0\) for every \(x\in X\) and \(S,T\in\mathcal B(X)\), then ...
