What is ... a syzygy?

This page hosts information on Daniele Agostini's talk "What is ... a syzygy?" at the "What is ...?" seminar. The talk will take place on Friday, October 24, 4:00pm at HU, RUD 25 1.023.


In astronomy, a "syzygy" is an alignment of three celestial bodies. The term was imported into mathematics by Sylvester to denote a linear relation between the generators of a module. Nowadays, syzygies and, more generally, free resolutions are powerful tools to relate the algebra and geometry of a projective variety. In this talk I will introduce these concepts and present some concrete examples.
