Periodic Reporting for period 2 - REFINV (Refined invariants in combinatorics, low-dimensional topology and geometry of moduli spaces)

Some invariants appearing in low-dimensional topology and algebraic geometry admit a so-called refinement: a much stronger, but more complicated invariant. For instance, in low-dimensional topology we study the Poincare polynomial of the triply-graded Khovanov-Rozansky...
