Examples on Strongly Fillable  but not Stein Fillable Contact
3-manifolds: $(-\Sigma(2,
2g+1, 2(2g+1)n-1), \mu_{0})$


In this talk, we will show that the $3$-manifold $-\Sigma(2, 2g+1,
2(2g+1)n-1)$ admits a contact structure $\mu_{0}$ which is strongly
fillable but not Stein fillable. We will explain how to produce
$(-\Sigma(2,2g+1, 2(2g+1)n-1), \mu_{0})$ and show that  $\mu_{0}$  is
strongly symplectically filllable. If time permit, we will prove the
non-Stein fillability of $\mu_{0}$ using the contact invariants in
Heegaard-Floer theory.
