  報告摘要:

  In tau-tilting theory, left Bongartz completion (or Bongartz co-completion) is an operation to complete a tau-rigid pair (U,Q) to the minimal tau-tilting pair (M,P) containing (U,Q) as a direct summand. In this talk, we will introduce relative version of left Bongartz completion, which gives a family of completions of (U,Q)。 We show that relative left Bongartz completions have nice compatibility with mutations of tau-tilting pairs. Some applications to this compatibility will be mentioned.
