Homotopy coherent Gysin functoriality

Frédéric Déglise, Niels Feld, Fangzhou Jin

We construct homotopy coherent Gysin pullbacks for weak Borel-Moore theories on smooth schemes, addressing the higher coherence problem for Gysin morphisms associated with closed i…

Homological Milnor-Witt modules and Chow-Witt groups over general bases

Frédéric Déglise, Niels Feld, Fangzhou Jin

We introduce a general theory of homological Milnor-Witt cycle modules over an excellent base scheme equipped with a dimension function, extending both Rost's cycle modules and Fel…

Moving lemmas and the homotopy coniveau tower

Frédéric Déglise, Niels Feld, Fangzhou Jin

In this note we study the functoriality of the coniveau filtration in motivic homotopy theory via a moving lemma over a base scheme, extending previous works of Levine and Bachmann…

Perverse homotopy heart and MW-modules

Frédéric Déglise, Niels Feld, Fangzhou Jin

We compute the perverse delta-homotopy heart of the motivic stable homotopy category over a base scheme with a dimension function delta, rationally or after inverting the exponenti…

Transfers on Milnor-Witt K-theory

Niels Feld

We give a new proof of the fact that Milnor-Witt K-theory has geometric transfers. The proof yields to a simplification of Morel's conjecture about transfers on contracted homotopy…

MW-homotopy sheaves and Morel generalized transfers

Niels Feld

We explore a conjecture of Morel about the Bass-Tate transfers defined on the contraction of a homotopy sheaf and prove that the conjecture is true with rational coefficients. More…
