Linear Algebra for Computer Scientists. 8. Convex Combinations of Vectors
This computer science video is one of a series on linear algebra for computer scientists. In this video you will learn about convex combinations of vectors. A convex combination is a special type of linear combination, in which the coefficients must add up to one, and are both greater tha

Nonlinear algebra, Lecture 13: "Polytopes and Matroids ", by Mateusz Michalek
This is the thirteenth lecture in the IMPRS Ringvorlesung, the advanced graduate course at the Max Planck Institute for Mathematics in the Sciences.
From playlist IMPRS Ringvorlesung - Introduction to Nonlinear Algebra
We have already looked at the column view of a matrix. In this video lecture I want to expand on this topic to show you that each matrix has a column space. If a matrix is part of a linear system then a linear combination of the columns creates a column space. The vector created by the

John R. Parker: Complex hyperbolic lattices
Lattices in SU(2,1) can be viewed in several different ways: via their geometry as holomorphic complex hyperbolic isometries, as monodromy groups of hypergeometric functions, via algebraic geometry as ball quotients and (sometimes) using arithmeticity. In this talk I will describe these di

Stefan Weltge: Lattice-free simplices with lattice width 2d - o(d)
The Flatness theorem states that the maximum lattice width Flt(d) of a d-dimensional lattice-free convex set is nite. It is the key ingredient for Lenstra's algorithm for integer programming in xed dimension, and much work has been done to obtain bounds on Flt(d). While most results have b

Kazuo Murota: Extensions and Ramifications of Discrete Convexity Concepts
Submodular functions are widely recognized as a discrete analogue of convex functions. This convexity view of submodularity was established in the early 1980's by the fundamental works of A. Frank, S. Fujishige and L. Lovasz. Discrete convex analysis extends this view to broader classes of

Daniel Dadush: Integer Programming and the Kannan-Lovasz Conjecture
In this talk, I will give a (very) high-level overview of the lattice theoretic and convex geometric tools needed to solve n-variable integer programs in O(n)n time. In the process, I will introduce the Kannan-Lovasz conjecture, which posits the existence of very sparse lattice projections
