Outline of the course: The aim of this course is to provide an introduction to the theory of motives. Motives in algebraic geometry were introduced 40 years ago or so with the purpose of finding a common source for several cohomological theories and cohomological phenomena such as the notion of weight. The goal of this theory is that of decomposing, cohomologically, the algebraic varieties in simple fundamental blocks suitable of being (re)combined together. Very recently, the theory of motives has been also used to explain mathematically, the appearance of multiple zeta values in anomalous dimensions and \beta functions of renormalizable quantum field theories and it has also established interesting connections with noncommutative geometry and quantum statistical mechanics.
Prerequisites: This is the second part of 110.643. Those students who did not enroll in 110.643 should be acquainted with the topics developed in that course. Students should also be acquainted with the fundamental notions of algebraic and differential geometry, commutative algebra and algebraic topology such as: Zariski topology, algebraic varieties, sheaf theory, notions of Weil cohomological theories: Betti, de Rham..., vector bundles, homological algebra, spectral sequences.
Grading: Some exercises will be assigned regularly during lectures. The exercises will not be collected, and in fact there will be no written work required in this course. The final grade will be determined from class participation, that basically means did you attend *all* lectures and try to ask questions with some frequency and also answer questions posed by the instructor?
Important Notes: First class: Tuesday January 23.

Classes will be cancelled during the weeks of March 26-28 and April 2-4, as the instructor will be away.
