## Topology Seminar - Radmila Sazdanovic; NC State University

Monday, October 14, 2024 11:30am to 12:20pm

Title: TDA and knot theory
Abstract: In 1987, Ernst and Summers demonstrated that the number of knots increases exponentially with the number of crossings, effectively categorizing knots as big data. Consequently, big data techniques offer a novel approach to analyzing knots and their invariants. This talk will focus on employing tools from topological data analysis (TDA) and AI to explore the space of knots and their invariants.

## Panorama of Geology and Topology (Undergraduate Colloquium) - Radmila Sazdanovic; NC State University

Monday, October 14, 2024 5:00pm to 6:00pm

Title: The shape of relations: games, knots and other stories
Abstract: Literature Nobel prize winner A. Solzhenitsyn wrote: "Topology! The stratosphere of human thought! In the XXIV century it might just possibly be of use to somebody, ...". Developed in the XXI century, Topological Data Analysis (TDA) offers powerful methods for uncovering patterns in complex datasets by analyzing their shape. In this talk, we will explore tools for visualizing high-dimensional maps and detecting relations...
