The Gompf -Invariant of Canonical Contact Structures via Legendrian Surgery
Mohan Bhupal, Burak Ozbagci
Let be a minimal connected negative-definite plumbing tree with all vertices of genus zero, and let be the oriented link of the corresponding normal complex surface sin…
Complementary legs and symplectic rational balls
John B. Etnyre, Burak Ozbagci, Bülent Tosun
We show that a small Seifert fibered space with complementary legs does not symplectically bound a rational homology ball for at least one choice of orientation. In the case $e_0\l…
Unbraided wiring diagrams for Stein fillings of lens spaces
Mohan Bhupal, Burak Ozbagci
In a previous work, we constructed a planar Lefschetz fibration on each Stein filling of any lens space equipped with its canonical contact structure. Here we describe an algorithm…
Symplectic rational homology ball fillings of Seifert fibered spaces
John B. Etnyre, Burak Ozbagci, Bülent Tosun
We characterize when some small Seifert fibered spaces can be the convex boundaries of symplectic rational homology balls and give strong restrictions for others to bound such mani…
