Birational cubic fourfolds via an Enriques Cremona transformation<\/h2>\n

Lisa Marquand <\/strong>, Rutgers University<\/p>\n

Abstract:<\/strong> Let X be a very general cubic fourfolds containing an Enriques surface. Such a cubic is conjecturally irrational. A conjecture of Huybrechts predicts that there exists a unique non isomorphic cubic fourfolds Y birational to X. We explicitly construct Y via a new Cremona transform of the ambient projective space and verify the conjecture.<\/p>\n

This is joint work with Corey Brooke.<\/p>\n<\/div>\n

Rank and level for symplectic and orthogonal groups<\/h2>\n

Yuqiao Huang<\/strong>, Rutgers University<\/p>\n

Abstract:<\/strong> The level and the rank of characters of finite classical groups have been studied in the work of Guralnick, Larsen, and Tiep (Forum Math. Pi 2020; Invent. Math. 2024). Following their strategy, we establish similar results, for finite symplectic groups in odd characteristic, and for finite orthogonal groups in characteristic 2<\/p>\n<\/div>\n

The characteristic polynomial of finite dimensional algebras<\/h2>\n

Rongwei Yang<\/strong>, University of Albany\/SUNY<\/p>\n

Abstract: <\/strong> For a tuple of square matrices $A=(A_1, …, A_n)$ of equal size, its characteristic polynomial is defined as $\\det (z_0I+z_1A_1+\\cdots +z_nA_n)$, where I is the identity matrix and z_j are complex variables. If ${\\mathcal A}$ is a n-dimensional complex algebra, then its structure constants give rise to n square matrices of size n. The characteristic polynomial of the structural matrices enables one to study the algebra ${\\mathcal A}$ using geometric, topological, and number theoretic means. In this talk, we will consider examples involving Lie algebras and finite groups.<\/p>\n<\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
