Derived equivalences and Kodaira fibers
[摘要] We give necessary conditions for two (including non-reduced and multiple) Kodaira curves to be derived equivalent. We classify Fourier Mukai partners of any reduced Kodaira curve. We prove that the derived category of singularities of any non-reduced and non-multiple Kodaira curve is idempotent complete. (C) 2017 Elsevier B.V. All rights reserved.
