Watch a 48-minute mathematics lecture exploring the application of motivic obstruction techniques to solve rationality problems in algebraic geometry. Delve into the groundbreaking research demonstrating that very general quartic fivefolds and complete intersections of quadric and cubic in P^6 are stably irrational, achieved through innovative tropical degeneration techniques. Learn from collaborative work between the speaker and Johannes Nicaise, presented at the "Logarithmic and non-archimedean methods in Singularity Theory" conference at Centre International de Rencontres Mathématiques in Marseille, France. Access this enriched educational content through CIRM's Audiovisual Mathematics Library, featuring chapter markers, keywords, abstracts, bibliographies, and Mathematics Subject Classification for enhanced learning and reference.
