COUNTING REAL J-HOLOMORPHIC DISCS AND SPHERES IN DIMENSION FOUR AND SIX
We provide another proof that the signed count of the real Jholomorphic spheres (or J-holomorphic discs) passing through a generic real configuration of k points is independent of the choice of the real configuration and the choice of J, if the dimension of the Lagrangian submanifold L (fixed point...

Summary: | We provide another proof that the signed count of the real Jholomorphic
spheres (or J-holomorphic discs) passing through a generic
real configuration of k points is independent of the choice of the real
configuration and the choice of J, if the dimension of the Lagrangian
submanifold L (fixed point set of involution) is two or three, and also if
we assume L is orientable and relatively spin. We also assume that M is
strongly semi-positive. This theorem was first proved by Welschinger in
a more general setting, and we provide more natural approach using the
signed degree of an evaluation map. KCI Citation Count: 16 |
