Improved Bounds for Perfect Sampling of $k$ -Colorings in Graphs

Siddharth Bhandari, Sayantan Chakraborty

We present a randomized algorithm that takes as input an undirected $n$ -vertex graph $G$ with maximum degree $Δ$ and an integer $k > 3Δ$ , and returns a random proper $k$ -coloring o…

Smooth Connes--Thom isomorphism, cyclic homology, and equivariant quantisation

Sayan Chakraborty, Xiang Tang, Yi-Jun Yao

Using a smooth version of the Connes--Thom isomorphism in Grensing's bivariant K-theory for locally convex algebras, we prove an equivariant version of the Connes--Thom isomorphism…

A note on crossed products of rotation algebras

Christian Bönicke, Sayan Chakraborty, Zhuofeng He +1

We compute the $K$ -theory of crossed products of rotation algebras $A_{θ}$ , for any real angle $θ$ , by matrices in $SL (2, Z)$ with infinite order. Using te…
