A comprehensive textbook/reference to learn/use derived categories and their applications in commutative algebra (Grothendieck local duality etc.) Review: zbmath.org/7954534 Sample chapter: rdcu.be/eyl8d Book: link.springer.com/book/10.1007/9…
"a new and conclusive presentation of the homological methods [...] a very useful, up-to-date reference book for working mathematicians" writes Peter Schenzel in @zbMATH about the book Derived Category Methods in Commutative Algebra by Christensen, Foxby (†) and Holm. (1/2)
Saddened to hear of the passing of the combinatorialist U.S.R. Murty (en.wikipedia.org/wiki/U._S._R._…). A professor at @UWaterloo, he was the co-author (w/J.A. Bondy) of the successful GTM 'Graph Theory' and just last year published a monograph on 'Perfect Matchings' (w/C.L. Lucchesi).
