Extremal graphs for clique-paths

Roman Glebov

In this paper we deal with a Turán-type problem: given a positive integer n and a forbidden graph H, how many edges can there be in a graph on n vertices without a subgraph H? How…

On extremal hypergraphs for hamiltonian cycles

Roman Glebov, Yury Person, Wilma Weps

We study sufficient conditions for Hamiltonian cycles in hypergraphs, and obtain both Turán- and Dirac-type results. While the Turán-type result gives an exact threshold for the ap…

On covering expander graphs by Hamilton cycles

Roman Glebov, Michael Krivelevich, Tibor Szabó

The problem of packing Hamilton cycles in random and pseudorandom graphs has been studied extensively. In this paper, we look at the dual question of covering all edges of a graph…

Brick polytopes of spherical subword complexes and generalized associahedra

Vincent Pilaud, Christian Stump

We generalize the brick polytope of V. Pilaud and F. Santos to spherical subword complexes for finite Coxeter groups. This construction provides polytopal realizations for a certai…

Acyclic systems of permutations and fine mixed subdivisions of simplices

Federico Ardila, Cesar Ceballos

A fine mixed subdivision of a (d-1)-simplex T of size n gives rise to a system of permutations of [n] on the edges of T, and to a collection of n unit (d-1)-simplic…

An improved error term for minimum H-decompositions of graphs

Peter Allen, Julia Böttcher, Yury Person

We consider partitions of the edge set of a graph G into copies of a fixed graph H and single edges. Let ϕ_H(n) denote the minimum number p such that any n-vertex G admits such a p…
