Rationally isotropic quadratic spaces are locally isotropic

 Announcement

A well-known Colliot-Thélène’s conjecture asserts that a rationally isotropic quadratic space over a regular local ring is isotropic. If the ring contains a field, then the conjecture was proved by the efforts of the speaker, Pimenov and Scully. In the talk we present this and new results.

Everyone is welcome!
