Contact Surgery Numbers of the 3-torus
Prerak Deep, Monika Yadav
We study contact surgery numbers for contact structures on the 3-torus. We show that all contact structures obtained via contact surgery along a Legendrian Borromean ring are overt…

On Contact Round Surgeries on and Their Diagrams
Prerak Deep, Dheeraj Kulkarni
We introduce the notion of contact round surgery of index on Legendrian knots in a general contact 3-manifold. It generalizes the notion of contact round surgery of index 1 on…

On Round Surgery Diagrams For 3-Manifolds
Prerak Deep, Dheeraj Kulkarni
We introduce the notion of round surgery diagrams in for representing 3-manifolds similar to Dehn surgery diagrams. We give a correspondence between a certain class of round…
