Query: Survey on homological flips and homological flops   We give a survey for the results in [Yeu20a, Yeu20b, Yeu20c], which attempts
to relate the derived categories under general classes of flips and flops. We
indicate how the approach fails because of what appears to be a formal problem.
We give some ideas, and record some failed attempts, to fix this problem. We
also present some new examples.
