Derived category in algebraic geometry
WebThe main idea of derived categories is simple: work with complexes rather than their (co)homology. We will take simple examples from algebraic geometry to demonstrate why one might want to do this, then examples from algebraic topology to show that the ideas and structure are already familiar. (The link between the WebDerived Categories Derived categories were initially conceived by Grothendieck as a device for main-taining cohomological data during his reformulation of algebraic …

WebJul 19, 2024 · I was looking for other results, but there is Fourier-Mukai transforms in algebraic geometry that also nicely explains derived categories and triangulated structures on them etc., but later on tries to actually use it to study (bounded) derived categories of (coherent) sheaves of modules on schemes. Webderived algebraic geometry, we need a formalism of “generalized rings” in which imposing the equation x= 0 twice is not equivalent to imposing the equation once. One way to …

WebIn the 1970s, Beilinson, Gelfand, and Gelfand discovered that a derived category of an algebraic variety may be equivalent to that of a finite-dimensional non-commutative algebra, and Mukai found that there are non-isomorphic algebraic varieties that have equivalent derived categories.
