This book combines foundational constructions in the theory of motives and results relating motivic cohomology to more explicit constructions. Prerequisite for understanding the work is a basic background in algebraic geometry. The author constructs and describes a triangulated category of mixed motives over an arbitrary base scheme. Most of the classical constructions of cohomology are described in the motivic setting, including Chern classes from higher $K$-theory, push-forward for proper maps, Riemann-Roch, duality, as well as an associated motivic homology, Borel-Moore homology and cohomology with compact supports.
The relations that could or should exist between algebraic cycles, algebraic K-theory, and the cohomology of - possibly singular - varieties, are the topic of investigation of this book. The...
Historically, this book is the first to give a complete construction of a triangulated category of mixed motives with rational coefficients satisfying the full Grothendieck six functors formalism as well as fulfilling Beilinson’s program, ...
Mixed Motives and Their Realization in Derived Categories
are directly related, and one expects a description of the whole Chow group and a satisfactory treatment of arbitrary varieties in the setting of a category of mixed motives [Bei 4 J , [D1 O] . Finally, work of Beilinson suggests that ...
This includes a review of several known cohomology theories. A new absolute cohomology is introduced and studied. The book assumes knowledge of the standard cohomological techniques in algebraic geometry as well as K-theory.
Beauregard is thrown every which way by seemingly unconnected deaths. So many possibilities exist for motive, but not one prevails. One step after another evidence is exposed, along with the truth.
Understanding the precise relation between residues of Feynman integrals and mixed Tate motives remains a question of crucial importance. There are two main obstacles in using the result of Proposition 1.110 and Corollary 1.111 to ...
This is a polynomial ring Z[L] ⊂ K0 (VK), or a ring of Laurent polynomials Z[L,L−1] ⊂ K0 (M(K)), which corresponds to the classes of varieties that motivically are mixed Tate motives. See the comment at the end of §2.6 below on the ...
El This (conjectural) proof of the Riemann hypothesis for motives is very close to Weil's original proof for abelian varieties [32]. Mixed motives over a finite field. THEOREM 2.49. Every mixed motive over a finite field is a direct sum ...
Homological motives. Consult [And04, §3.4] for the general notion of a Weil cohomology theory H∗. Examples include de Rham, Betti, étale, and crystalline cohomology. We focus ourselves on de Rham cohomology H∗dR.
