Reduced Open Gromov-Witten Invariants on K3 Surfaces and Multiple Cover   Formula
  In the paper, we study the wall-crossing phenomenon of reduced open Gromov-Witten invariants on K3 surfaces with rigid special Lagrangian boundary condition. As a corollary, we derived the multiple cover formula for the reduced open Gromov-Witten invariants.
