Description
After briefly reviewing the role of positivity in the numerical bootstrap, I will focus on cases where positivity is lost. Gliozzi's truncation method will be discussed, together with some of the variations introduced in later works. I will illustrate some strengths and weaknesses of the method, via examples drawn from non-unitary CFTs and unitary CFTs with a boundary.
If time permits, I will discuss some analytic consequences of the crossing equations in the presence of boundaries and defects.
