On k-factor-critical graphs [PDF]

open access: yesDiscussiones Mathematicae Graph Theory, 1996
Summary: A graph is said to be \(k\)-factor-critical if the removal of any set of \(k\) vertices results in a graph with a perfect matching. We study some properties of \(k\)-factor-critical graphs and show that many results on \(q\)-extendable graphs can be improved using this concept.

The planted k-factor problem [PDF]

open access: yesJournal of Physics A: Mathematical and Theoretical, 2021
Abstract We consider the problem of recovering an unknown k-factor, hidden in a weighted random graph. For k = 1 this is the planted matching problem, while the k = 2 case is closely related to the planted traveling salesman problem.

A constant-factor approximation algorithm for reconciliation k-median [PDF]

open access: yes, 2023
In the reconciliation k-median problem we ask to cluster a set of data points by picking k cluster centers so as to minimize the sum of distances of the data points to their cluster centers plus the sum of pairwise distances between the centers.

The at-most $k$-deep factor tree [PDF]

open access: yes, 2004
We present a new data structure to index strings that is very similar to a suffix tree. The new structure indexes the factors of a string whose length does not exceed k, and only those.

Connected k-factors in bipartite graphs

open access: yesDiscrete Mathematics, 2023
Let $k,l$ be two positive integers. An $S_{k,l}$ is a graph obtained from disjoint $K_{1,k}$ and $K_{1,l}$ by adding an edge between the $k$-degree vertex in $K_{1,k}$ and the $l$-degree vertex in $K_{1,l}$. An {\em $S_{k,l}$-free} graph is a graph containing no induced subgraph isomorphic to $S_{k,l}$.

On unique k-factors and unique [1,k]-factors in graphs

open access: yesDiscrete Mathematics, 2004
Let \(G\) be a graph and let \(a\) and \(b\), \(a\leq b\), be two positive integers. A spanning subgraph \(F\) of \(G\) is an \([a,b]\)-factor if \(a\leq \deg_Fv\leq b\), for every vertex \(v\) in \(G\). A \([k,k]\)-factor is called a \(k\)-factor. An \([a,b]\)-factor is perfect if each of its components is a regular graph.

Amalgamations of connected k-factorizations

open access: yesJournal of Combinatorial Theory, Series B, 2003
Let \(G\) be an edge-colored graph on the set of colors \(\{ 1,2,\ldots,n\}\), and let \(P\) be a partition of \(V(G)\). The \(P\)-amalgamation of \(G\) is the \(n\)-edge-colored graph with vertex set \(P\), in which \(p\in P\) is incident with \(y\) loops colored \(i\) if and only if there are \(y\) loops or edges in \(G\) that join vertices in \(p\),
