Log canonical thresholds of high multiplicity reduced plane curves
Erik Paemurru, Nivedita Viswanathan
We compute log canonical thresholds of reduced plane curves of degree at points of multiplicity . As a consequence, we describe all possible values of log canonical thresh…

Counting divisorial contractions with centre a -singularity
Erik Paemurru
First, we simplify the existing classification due to Kawakita and Yamamoto of 3-dimensional divisorial contractions with centre a -singularity, also called compound si…

Reading the log canonical threshold of a plane curve singularity from its Newton polyhedron
Erik Paemurru
There is a proposition due to Kollár 1997 on computing log canonical thresholds of certain hypersurface germs using weighted blowups, which we extend to weighted blowups with non-…
