On the induced matching problem

open access: yesJournal of Computer and System Sciences, 2011
We study extremal questions on induced matchings in several natural graph classes. We argue that these questions should be asked for twinless graphs, that is graphs not containing two vertices with the same neighborhood. We show that planar twinless graphs always contain an induced matching of size at least $n/40$ while there are planar twinless graphs

Phase-matching free pulse retrieval based on plasma-induced defocusing [PDF]

open access: yesEPJ Web of Conferences, 2023
A phase-matching free pulse retrieval technique based on plasma-induced defocusing in a rare gas is presented. Based on a pump-probe setup, this technique uses a moderately intense pump laser pulse for ionizing the medium, creating in turn an ultrafast ...

Matching book thickness of generalized Petersen graphs

open access: yesElectronic Journal of Graph Theory and Applications, 2022
The matching book embedding of a graph G is to place its vertices on the spine, and arrange its edges on the pages so that the edges in the same page do not intersect each other and the edges induced subgraphs of each page are 1-regular.

Antimatroids induced by matchings [PDF]

open access: yesDiscrete Applied Mathematics, 2019
We explore novel connections between antimatroids and matchings in bipartite graphs. In particular, we prove that a combinatorial structure induced by stable matchings or maximum-weight matchings is an antimatroid. Moreover, we demonstrate that every antimatroid admits such a representation by stable matchings and maximum-weight matchings.

Large Induced Matchings in Random Graphs [PDF]

open access: yesSIAM Journal on Discrete Mathematics, 2021
Given a large graph $H$, does the binomial random graph $G(n,p)$ contain a copy of $H$ as an induced subgraph with high probability? This classical question has been studied extensively for various graphs $H$, going back to the study of the independence number of $G(n,p)$ by Erdős and Bollobás, and Matula in 1976.

A faster algorithm for maximum independent set on interval filament graphs

open access: yesJournal of Graph Algorithms and Applications, 2022
We provide an algorithm requiring only $O(N^2)$ time to compute the maximum weight independent set in an $N$-vertex interval filament graph. This implies an $O(N^4)$-time algorithm to compute the maximum weight induced matching in such graphs.

On price-induced minmax matchings

open access: yesCoRR, 2023
We study a natural combinatorial pricing problem for sequentially arriving buyers with equal budgets. Each buyer is interested in exactly one pair of items and purchases this pair if and only if, upon arrival, both items are still available and the sum of the item prices does not exceed the budget.
