Abstract: We study the isoperimetric and spectral profiles of certain families of finitely generated groups defined via actions on labelled Schreier graphs and simple gluing of such. In one of our simplest constructions—the pocket-extension of a… read more here.

Abstract: We consider groups defined by non-empty balanced presentations with the property that each relator is of the form R(x,y), where x and y are distinct generators and R(.,.) is determined by some fixed cyclically reduced… read more here.

Abstract: A graph Γ labeled by a set S defines a group G(Γ) whose set of generators is the set S of labels and whose relations are all words which can be read on closed paths… read more here.

DOI: 10.1161/jaha.121.021724
Abstract: Background All of Us is a novel research program that aims to accelerate research in populations traditionally underrepresented in biomedical research. Our objective was to evaluate the burden of cardiovascular disease (CVD) in broadly defined… read more here.
