Upper bounds for the Laplacian spectral radius: Proofs and counterexamples

Ivan Damnjanović, Taewoo Ha, Dragan Stevanović

The Laplacian spectral radius of a graph is the largest eigenvalue of its Laplacian matrix. Previously, upper bounds for the Laplacian spectral radius were proposed using a backwar…

Some results on small ordered and cyclic Ramsey numbers

Nino Bašić, Ivan Damnjanović, Dragan Stevanović +1

Let $k \in N$ and let $H_{1}, H_{2}, \dots, H_{k}$ be simple graphs such that for each $j \in {1, 2, \dots, k}$ , the vertex set of $H_{j}$ is $\{ 0, 1, 2, \ldots, n_j - 1 \}…
