Fractional Matching Via Balls-and-Bins
In this paper we relate the problem of finding structures related to perfect matchings in bipartite graphs to a stochastic process similar to throwing balls into bins. Given a bip...

On planar intersection graphs with forbidden subgraphs
Let C be a family of n compact connected sets in the plane, whose intersection graph G(C) has no complete bipartite subgraph with k vertices in each of its classes. Then G(C) has ...

Maximum Bipartite Matching Size And Application to Cuckoo Hashing
Cuckoo hashing with a stash is a robust high-performance hashing scheme that can be used in many real-life applications. It complements cuckoo hashing by adding a small stash stor...

The vertex isoperimetric problem for the powers of the diamond graph
We introduce a new graph for all whose cartesian powers the vertex isoperimetric problem has nested solutions. This is the fourth kind of graphs with this property besides the wel...

Regular Sparse Crossbar Concentrators
A bipartite concentrator is a single stage sparse crossbar switching device that can connect any m of its n ≥ m inputs to its m outputs possibly without the ability to distingui...
