Abstract

In fall of 2019, the Thursday Seminar at Harvard University studied motivic infinite loop space theory. As part of this, the authors gave a series of talks outlining the main theorems of the theory, together with their proofs, in the case of infinite perfect fields. These are our extended notes on these talks.

Comments

mainly expository; 38 pages; v2: include treatment of strict A1-invariance; v3: remove erroneous claim (Lemma 3.23) and rewrite Section 3.5 to work around this
