A remark on Kähler forms on symmetric products of Riemann surfaces
Abstract
Description
Users of Heegaard Floer homology may be reassured to know that it can be made to conform exactly to the standard analytic pattern of Lagrangian Floer homology. This follows from the following remark, which we prove using an argument of J. Varouchas: the natural singular Kähler form $\sym^n(ω)$ on the $n$th symmetric product of a Kähler curve $(Σ,ω)$ admits a cohomologous smoothing to a Kähler form which equals $\sym^n(ω)$ away from a chosen neighbourhood of the diagonal.
