Measures of string similarities based on the Hamming distance
Bojan Nikolić, Boris Šobot
In this paper we consider measures of similarity between two sets of strings built up using the Hamming distance and tools of persistence homology as a basis. First we describe the…

Multiplicative finite embeddability vs divisibility of ultrafilters
Boris Šobot
We continue the exploration of various aspects of divisibility of ultrafilters, adding one more relation to the picture: multiplicative finite embeddability. We show that it lies b…
