Some remarks on convex analysis in topological groups

Jonathan M. Borwein, Ohad Giladi

We discuss some key results from convex analysis in the setting of topological groups and monoids. These include separation theorems, Krein-Milman type theorems, and minimax theore…

Convex analysis in groups and semigroups: a sampler

Jonathan M. Borwein, Ohad Giladi

We define convexity canonically in the setting of monoids. We show that many classical results from convex analysis hold for functions defined on such groups and semigroups, rather…

Nearest points and delta convex functions in Banach spaces

Jonathan M. Borwein, Ohad Giladi

Given a closed set $C$ in a Banach space $(X, ∥ \cdot ∥)$ , a point $x \in X$ is said to have a nearest point in $C$ if there exists $z \in C$ such that $d_{C} (x) = ∥ x - z ∥$ , where $d_{C}$ …

Inverse Littlewood-Offord problems for Quasi-Norms

Omer Friedland, Ohad Giladi, Olivier Guédon

Given a star-shaped domain $K \subseteq R^{d}$ , $n$ vectors $v_{1}, \dots, v_{n} \in R^{d}$ , a number $R > 0$ , and i.i.d. random variables $η_{1}, \dots, η_{n}$ , we study the geometri…
