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…

Monodromy factorizations of lines on del Pezzo surfaces
Mohan Bhupal, Sergey Finashin
We give a list of monodromy factorizations in the pure mapping class group of a torus with d+1 marked points that represent lines on a del Pezzo surface Y of degree…
