Title: Upsilon invariants from cyclic branched covers

Abstract: Studying the knot Floer homology of the pull-back of a knot
to its m-fold cyclic branched cover (m=p^r a prime power) one can
construct a one-parameter family of knot concordance invariants
Upsilon_{K,m}(t). Using involutive knot Floer homology the same circle
of ideas can be used to produce knot concordance invariants
\underline{U}_{K,m}(t) <= U_{K,m}(t)<= \overline{U}_{K,m}(t).  I will
discuss these constructions and point out some possible applications.
This is a joint project with Andras Stipsicz, Andras Nemethi, and
Daniele Celoria.
