Biextensions of 1-motives by 1-motives
Let S be a scheme. In this paper, we define the notion of biextensions of 1-motives by 1-motives. Moreover, if M(S) denotes the Tannakian category generated by 1-motives over S (in a geometrical sense), we define geometrically the morphisms of M(S) from the tensor product of two 1-motives M1⊗M2 to another 1-motive M3, to be the isomorphism classes of biextensions of (M1, M2) by M3: HomM(S)(M1 ⊗...
متن کاملBirational motives, I: pure birational motives
In the preprint [19], we toyed with birational ideas in three areas of algebraic geometry: plain varieties, pure motives in the sense of Grothendieck, and triangulated motives in the sense of Voevodsky. These three themes are finally treated separately in revised versions. The first one was the object of [21]; the second one is the object of the present paper; we hope to complete the third one ...

متن کاملMeasuring implicit motives 1 RUNNING HEAD: Measuring implicit motives Measuring implicit motives
All picture stimuli described in this chapter are available upon request from the authors. Measuring implicit motives 2 Measuring implicit motives Over the past ten years, the field of personality psychology has seen a resurgence of interest in implicit motives, nonconscious motivational needs that orient, select, and energize behavior (McClelland, 1987). This renewed interest has led to signif...
متن کاملClassical motives
There is therefore little which is original contained in these pages. I have given a more or less complete proof of Murre’s result in §4, so as to make the comparison between the different decompositions in 5.3. Also included is a proof (3.5) of the unsurprising fact that the category of motives constructed using rational equivalence of cycles is in general not an abelian category. Otherwise pr...
