We prove that a strong version of Chang's Conjecture together with [Formula: see text] implies there are no [Formula: see text]-Aronszajn trees. ...

Define a point in a topological space to be homotopically fixed if it is fixed by every self-homotopy of the space, i.e. every self-map of the space which is homotopic to the identity, and define a point to be one-dimensional if it has a ne...

Every Peano continuum has a strong deformation retract to a deforested continuum, that is, one with no strongly contractible subsets attached at a single point. In a deforested continuum, each point with a one-dimensional neighborhood is ei...
Random state transitions of knots: a first step towards modeling unknotting by type II topoisomerases [0.03%]

Type II topoisomerases are enzymes that change the topology of DNA by performing strand-passage. In particular, they unknot knotted DNA very efficiently. Motivated by this experimental observation, we investigate transition probabilities be...
