The challenge of solving energy distribution grid planning problems, including operation and expansion planning, stems from their combinatorial nature and the vast solution space. Several models and techniques have been proposed in the literature to...

Christol's theorem (1979), which sets ground for many interactions between theoretical computer science and number theory, characterizes the coefficients of a formal power series over a finite field of positive characteristic $p>0$ that satisfy an...

The classical McKay correspondence shows that there is a bijection between irreducible representations of finite subgroups $G$ of $\mathrm{SL}(2,\mathbb{C})$ and the exceptional divisors of the minimal resolution of the singularity $\mathbb{C}^2/G$...

Bregman proximal-type algorithms, such as mirror descent, are popular in optimization and data science for effectively exploiting problem structures and optimizing them under tailored geometries. However, most of existing convergence results rely on...

Introduced by Tate in 1957, a Koszul-Tate resolution allows one to replace any algebra with a free differential graded algebra. This can be used to compute important invariants of the original algebra such as BRST cohomology or cotangent cohomology...

Testing Gravity 2025 will be the 5th Testing Gravity conference hosted by Simon Fraser University. Held at the SFU Harbour Centre from January 29 - February 1, 2025, it will bring together leading experts on various ways of testing laws of gravity...

Let $E/\mathbb{Q}$ be an elliptic curve without complex multiplication. By Serre's open image theorem, the mod $\ell$ Galois representation $\overline{\rho}_{E, \ell}$ of $E$ is surjective for each prime number $\ell$ that is sufficiently large...

The question of which nilpotent Lie algebras admit complex structures is far from being understood. In recent decades, progress has primarily focused on providing algebraic obstructions to the existence of such structures, with classification results...

Distinguished representations are representations of a reductive group $G$ on a vector space $V$ such that there exists a $H$-invariant linear form for a subgroup $H$ of $G$. They intervene in the Plancherel formula in a relative setting, as well as...

The COVID-19 Pandemic placed considerable strain on intensive care units, and the critical care system in British Columbia and worldwide. I will review the critical care system and how it responded to the COVID-19 pandemic. During the first wave of...
