Framed motivic $\Gamma$-spaces
Abstract
We combine several mini miracles to achieve an elementary understanding of infinite loop spaces and very effective spectra in the algebro-geometric setting of motivic homotopy theory. Our approach combines -spaces and framed correspondences into the concept of framed motivic -spaces; these are continuous or enriched functors of two variables that take values in motivic spaces and are equipped with a framing. We craft proofs of our main results by imposing further axioms on framed motivic -spaces such as a Segal condition for simplicial Nisnevich sheaves, cancellation, - and -invariance, Nisnevich excision, Suslin contractibility, and grouplikeness. This adds to the discussion in the literature on coexisting points of view on the -homotopy theory of algebraic varieties.
