Combinatorial scientific computing /
Published c201“…Several discrete combinatorial problems and data structures, such as graph and hypergraph partitioning, supernodes and elimination trees, vertex and edge reordering, vertex and edge coloring, and bipartite graph matching, arise in these contexts. As an example, parallel partitioning tools can be used to ease the task of distributing the computational workload across the processors. …”

On a problem of El-Zahar and Erdős
Published 2023“…This, together with excluding <i>K<sub>t</sub></i>, is <i>not</i> enough to guarantee two anticomplete subgraphs both with large minimum degree; but it works if instead of excluding <i>K<sub>t</sub></i> we exclude the complete bipartite graph <i>K<sub>t,t</sub></i>. More exactly: for all <i>t</i>, <i>c</i> ≥ 1 there exists <i>d</i> ≥ 1 such that if <i>G</i> has minimum degree at least <i>d</i>, and does not contain the complete bipartite graph <i>K<sub>t,t</sub></i> as a subgraph, then there are two anticomplete subgraphs both with minimum degree at least <i>c</i>.…”

Bisplit graphs satisfy the Chen-Chv\'atal conjecture
Published 2019-05-01“…A graph is bisplit if its vertex set can be partitioned into three stable sets with two of them inducing a complete bipartite graph. We prove that these graphs satisfy the Chen-Chv\'atal conjecture: their metric space (in the usual sense) has a universal line (in an unusual sense) or at least as many lines as the number of vertices.…”
