On the induced matching problem [PDF]
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

On Graphs with Induced Matching Number Almost Equal to Matching Number
Abstract Kobler and Rotics in 2003, and Cameron and Walker in 2005, gave a complete structural description of the graphs G where the matching number ν ( G ) equals the induced matching number ν 2 ( G ) . We study their result and use it to analyse graphs G with ν ( G ) − ν 2 ( G ) ≤ k .

Antimatroids induced by matchings [PDF]
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]
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.

On price-induced minmax matchings
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.

Induced Matchings in Subcubic Graphs [PDF]
We prove that a cubic graph with $m$ edges has an induced matching with at least $m/9$ edges. Our result generalizes a result for planar graphs due to Kang, Mnich, and Müller (Induced matchings in subcubic planar graphs, SIAM J. Discrete Math. 26 (2012) 1383-1411) and solves a conjecture of Henning and Rautenbach (Induced matchings in subcubic graphs ...
