The diameter of products of finite simple groups
Following partially a suggestion by Pyber, we prove that the diameter of a product of non-abelian finite simple groups is bounded linearly by the maximum diameter of its factors. For completeness, we
G R ] 3 F eb 2 01 4 Finiteness results for subgroups of finite extensions
We discuss in the context of finite extensions two classical theorems of Takahasi and Howson on subgroups of free groups. We provide bounds for the rank of the intersection of subgroups within
Two-Bridge Knots and Residual Torsion-Free Nilpotence
The residual torsion-free nilpotence of the commutator subgroup of a knot group has proven to be an important property with applications to ribbon concordance and bi-orderability. In a lecture,
Group extensions and graphs
A classical result of Gaschütz affirms that given a finite A-generated group G and a prime p, there exists a group G# and an epimorphism φ : G# −→ G whose kernel is an elementary abelian p-group
Schreier Graphs and Ergodic Properties of Boundary Actions
This thesis is broadly concerned with two problems: investigating the ergodic properties of boundary actions, and investigating various properties of Schreier graphs. Our main result concerning the
On amalgamation of partially ordered monoids
On the Word Problem for Tensor Products and Amalgams of Monoids
We prove that the word problem for the free product with amalgamation S *UT of monoids can be undecidable, even when S and T are finitely presented monoids with word problems that are decidable in
A converse to Schreier's index-rank formula
In "Subgroups of free profinite groups and large subfields of Q" (Israel J. Math. 39 (1981), no. 1-2, pages 25-45; MR 617288) A. Lubotzky and L. van den Dries raise the question whether a finitely
Graph isomorphisms in quasi-polynomial time
Let us be given two graphs $\Gamma_1$, $\Gamma_2$ of $n$ vertices. Are they isomorphic? If they are, the set of isomorphisms from $\Gamma_1$ to $\Gamma_2$ can be identified with a coset $H\cdot\pi$
