A note on the weak splitting number

Alberto Cavallo, Carlo Collari, Anthony Conway

The weak splitting number $w s p (L)$ of a link $L$ is the minimal number of crossing changes needed to turn $L$ into a split union of knots. We describe conditions under which certai…

Locally equivalent Floer complexes and unoriented link cobordisms

Alberto Cavallo

We show that the local equivalence class of the collapsed link Floer complex $c C F L^{\infty} (L)$ , together with many $Υ$ -type invariants extracted from this group, is a concordance in…

An elementary computation of the Galois groups of symmetric sextic trinomials

Alberto Cavallo

We compute the Galois group of the splitting field $F$ of any irreducible and separable polynomial $f (x) = x^{6} + a x^{3} + b$ with $a, b \in K$ , a field with characteristic different from two…
