This is Josué Tonelli Cueto's talk "What is... semialgebraic sets in context?" at the "What is ...?" seminar. The talk was given on Friday, June 29, 2018, 1.00pm at Urania.
Semialgebraic sets are a quite general class of sets that can be described by reals polynomials and inequalities. In this talk, we will show how semialgebraic sets appear naturally in many different contexts: a) real algebraic geometry, b) discrete geometry, c) robotic arms and d) rigid models of molecules.
