The equivariant Milnor-Witt motive of $M_{1, 2}$

Nanjun Yang

We provide a decomposition of the equivariant Milnor-Witt motive for the moduli space of stable curves $M_{1, 2}$ . As a result, the equivariant Chow-Witt ring $…

Witt Group of Nondyadic Curves

Nanjun Yang

Witt group of real algebraic curves has been studied since Knebusch in 1970s. But few results are known if the base field is non-Archimedean except the hyperelliptic case by works…

On Tate Milnor-Witt Motives

Jean Fasel, Nanjun Yang

Smooth projective $G_{m}$ -varieties with isolated rational fixed points admit Tate Milnor-Witt motives. Over Euclidean fields, we give a splitting formula of such motives, w…

A generalization of the Arad--Ward theorem on Hall subgroups

N. Yang, A. A. Buturlakin

For a set of primes $I ¨ $ , denote by $E_{I ¨} $ the class of finite groups containing a Hall $I ¨ $ -subgroup. We establish that $E_{I ¨ _{1}} \cap E_{I ¨ _{2}}$ is contained in $E_{I ¨ _{1} \cap I ¨ _{2}}$ .…
