Some remarks on Gopakumar-Vafa invariants

Author(s): Schwarz, A.; Shapiro, I. | Abstract: We show that Gopakumar-Vafa invariants can be expressed in terms of the cohomology ring of moduli space of D-branes without reference to the sl_2 \times sl_2 action. We also give a simple construction of this action.
