Cohomology of complete intersections of quadrics
Jan Nagel
We show that the variable cohomology of a general complete intersection of quadrics can be identified with the intersection cohomology of a double covering. As a consequence, we sh…
Motivic decompositions of families with Tate fibers: smooth and singular cases
Mattia Cavicchi, Frédéric Déglise, Jan Nagel
We apply Wildeshaus's theory of motivic intermediate extensions to the motivic decomposition conjecture, formulated by Deninger-Murre and Corti-Hanamura. We first obtain a general…
The homotopy Leray spectral sequence
Aravind Asok, Frédéric Déglise, Jan Nagel
In this work, we build a spectral sequence in motivic homotopy that is analogous to both the Serre spectral sequence in algebraic topology and the Leray spectral sequence in algebr…
On complete intersections in varieties with finite-dimensional motive
Robert Laterveer, Jan Nagel, Chris Peters
Let be a complete intersection inside a variety with finite dimensional motive and for which the Lefschetz-type conjecture holds. We show how conditions on the nivea…
The hybrid Landau-Ginzburg models of Calabi-Yau complete intersections
Alessandro Chiodo, Jan Nagel
We observe that the state space of Landau-Ginzburg isolated singularities is simply a special case of Chen-Ruan orbifold cohomology relative to the generic fibre of the potential.…
Relative Chow-Kunneth decompositions for conic bundles and Prym varieties
Jan Nagel, Morihiko Saito
We construct a relative Chow-Kunneth decomposition for a conic bundle over a surface such that the middle projector gives the Prym variety of the associated double covering of the…
