Derived categories for the working mathematician | R. P. Thomas
; | Date: |
7 Dec 1999 | Journal: | Proceedings of the Winter School on mirror symmetry, vector bundles and lagrangian cycles, Harvard, January 1999. International Press 2001 | Subject: | Algebraic Geometry MSC-class: 18E30 | math.AG hep-th | Abstract: | It is becoming increasingly difficult for geometers and even physicists to avoid papers containing phrases like `triangulated category’, not to mention derived functors. I will give some motivation for such things from algebraic geometry, and show how the concepts are already familiar from topology. This gives a natural and simple way to look at cohomology and other scary concepts in homological algebra like Ext, Tor, hypercohomology and spectral sequences. | Source: | arXiv, math.AG/0001045 | Services: | Forum | Review | PDF | Favorites |
