On Berman-Gibbs stability and K-stability of $\mathbb{Q}$-Fano varieties [PDF]

open access: yesCompositio Mathematica, 2015
The notion of Berman-Gibbs stability was originally introduced by Robert Berman for $\mathbb{Q}$-Fano varieties $X$. We show that the pair $(X, -K_X)$ is K-stable (resp. K-semistable) provided that $X$ is Berman-Gibbs stable (resp.

Berman Codes: A Generalization of Reed-Muller Codes that Achieve BEC Capacity [PDF]

open access: yesInternational Symposium on Information Theory, 2022
We identify a family of binary codes whose structure is similar to Reed-Muller (RM) codes and which include RM codes as a strict subclass. The codes in this family are denoted as ${\mathcal{C}_n}(r,m)$, and their duals are denoted as ${{\mathcal{B}}_n}(r,

Approximation algorithms for node-weighted prize-collecting Steiner tree problems on planar graphs [PDF]

open access: yes, 2016
We study the prize-collecting version of the Node-weighted Steiner Tree problem (NWPCST) restricted to planar graphs. We give a new primal-dual Lagrangian-multiplier-preserving (LMP) 3-approximation algorithm for planar NWPCST.
