The next session of the Geometry Seminar of ICMS
will be held on Wednesday, February 28, 2024, at 16:00, in room 403 and via Zoom.
A talk on:
Linear embeddings of complex Grassmannians
will be delivered by Ivan Penkov, Constructor University Bremen.

Abstract: A linear embedding of Grassmannians, one of which could possibly be isotropic, is an embedding which respects the generators of Picard groups. Several years ago A.S. Tikhomirov and I classified such embeddings when both Grassmannians are simultaneously usual Grassmannians or isotropic Grassmannians of the same type(orthogonal or symplectic). In this talk I will discuss also the mixed case. A classification as above has an application to the classification of infinite-dimensional linear ind-Grassmannians, and I shall briefly explain this at the end of the talk.
