in mathematics, specifically in symplectic topology and algebraic
in mathematics, specifically in symplectic topology and algebraic geometry, gromov–witten (gw) invariants are rational numbers that, in certain situations, count pseudoholomorphic curves meeting prescribed conditions in a given symplectic manifold. the gw invariants may be packaged as a homology or cohomology class in ...
