Geometric construction of generators of CoHA of doubled quiver

Let Q be the double of a quiver. According to Efimov, Kontsevich and Soibelman, the cohomological Hall algebra (CoHA) associated with Q is a free super-commutative algebra. In this short note, we confirm a conjecture of Hausel, which gives a geometric realisation of the generators of the CoHA. (C) 2014 Academie des sciences. Published by Elsevier Masson SAS.
