On Matchings in Hypergraphs [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2012
We show that if the largest matching in a $k$-uniform hypergraph $G$ on $n$ vertices has precisely $s$ edges, and $n>2k^2s/\log k$, then $H$ has at most $\binom n k - \binom {n-s} k $ edges and this upper bound is achieved only for hypergraphs in which the set of edges consists of all $k$-subsets which intersect a given set of $s$ vertices.

Do Women Really Face Wage Discrimination on the Labour Market? An Analysis Using Intra-household Specialization

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2014
This study aims to estimate the gender pay gap, cleansed at least partially of the effect of intra-household specialization on productivity. The estimate is based on EU-SILC data for 19 member countries of the European Union.

Semantic Matching with S-Match [PDF]

open access: yes, 2009
We view matching as an operation that takes two graph-like structures (e.g., lightweight ontologies) and produces an alignment between the nodes of these graphs that correspond semantically to each other. Semantic matching is based on two ideas: (i) we discover an alignment by computing semantic relations (e.g., equivalence, more general); (ii) we ...

Near―perfect non-crossing harmonic matchings in randomly labeled points on a circle [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2005
Consider a set $S$ of points in the plane in convex position, where each point has an integer label from $\{0,1,\ldots,n-1\}$. This naturally induces a labeling of the edges: each edge $(i,j)$ is assigned label $i+j$, modulo $n$.

Pairing Optimization via Statistics: Algebraic Structure in Pairing Problems and Its Application to Performance Enhancement

open access: yesEntropy, 2023
Fully pairing all elements of a set while attempting to maximize the total benefit is a combinatorically difficult problem. Such pairing problems naturally appear in various situations in science, technology, economics, and other fields.

Designs of Branch-Line Couplers by Considering the Parasitic Effects of P-I-N Diodes

open access: yesIEEE Access, 2020
Branch-line couplers (BLCs) are commonly used in the wireless systems. To achieve reconfigurable applications, switchable BLCs with p-i-n diodes can be used.

Patterns in matchings and rook placements [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2013
Extending the notion of pattern avoidance in permutations, we study matchings and set partitions whose arc diagram representation avoids a given configuration of three arcs.

Bidirectional Matching Strategy for Multi-Controller Deployment in Distributed Software Defined Networking

open access: yesIEEE Access, 2018
Software defined networking (SDN) realizes the full decoupling between control plane and data plane, and it could effectively simplify network management and promote network innovation.
