Tristan Bice: Cardinal Invariants in the Calkin Algebra
Data: sexta-feira, 27 de novembro de 2015, às 10h
Sala: 241-A
Palestrante: Tristan Bice, UFBA
Título: Cardinal Invariants in the Calkin Algebra
Resumo: While cardinal invariants on $\wp(\omega)/Fin$ have been thoroughly investigated, the theory of their various projection analogs in $B(H)/K(H)$ is far less developed. In particular, we take a look at analogs of the MAD family and tower number and their relationship to their classical counterparts in $\wp(\omega)/Fin$.
