On the Tropical Discs Counting on Elliptic K3 Surfaces with General Singular Fibres
  Using Lagrangian Floer theory, we study the tropical geometry of K3 surfaces
with general singular fibres. In particular, we give the local models for the
type $I_n$, $II$, $III$ and $IV$ singular fibres in the Kodaira's
classification and generalize the correspondence theorem between open
Gromov-Witten invariants/tropical discs counting to these cases.
