The conservativity conjecture predicts that an algebraic correspondence between Chow motives is invertible if and only if its action on cohomology (e.g., de Rham cohomology) is invertible. (This includes as particular cases the Bloch conjecture on surfaces and the Kimura-O'Sullivan finite dimensionality conjecture for smooth hypersurfaces in ...

Sep 14, 2018 · Abstract: I will review the strategy of the proof of the conservativity conjecture for the classical realisations of Voevodsky motives over a characteristic zero fields. I will also mention some other consequences of this proof such as the nilpotence of endomorphisms acting by zero on cohomology.

Sep 26, 2019 · The conjecture is very easy to state and offers a bridge, or rather a return path to two different kinds of objects. One is a motive, which is a very rich algebraic geometric object, the other is its realisation which is a topological object with no additional structure. The conservativity structure turned out to be very difficult.

(Y, Y ∩ X). The conservativity universal is the conjecture that all determiners in all languages have this property. Such conjecture, as stated, is a descriptive statement. The question that naturally arises in this connection is where conservativity comes from. Some accounts have been Here is a partial answer: In characteristic 0 it is known that conservativity + algebraicity (edit: modulo rational equivalence) of the Künneth projectors implies the remaining standard conjectures. Indeed, if the Künneth projectors are algebraic, then one may use conservativity to show that the inverse of the Lefschetz operator is algebraic (i.e. Lefschetz standard conjecture). and formulate a conjecture which might be useful to construct a theory of epsilon factors.

The conservativity conjecture predicts that a correspondance between Chow motives is invertible if and only if its class in cohomology is invertible. I will discuss some aspects of a program aiming at proving the conservativity conjecture. More specifically, I'll try to explain how Hodge theory is used. Recorded Talk

In a more general setting, the conservativity theorem is formulated for extensions of a first-order theory by introducing a new functional symbol : Suppose that a closed formula is a theorem of a first-order theory , where we denote .
