Projected Wasserstein-Fisher-Rao Flows for Hawkes Background-Intensity Estimation

Isaias Banales, Arturo Jaramillo

We consider the problem of estimating the background intensity of a Hawkes process when the triggering mechanism is known, treating the background as an unknown finite positive mea…

Equivariant generating hypotheses for finite groups

Sihao Ma, XiaoLin Danny Shi, Zhouli Xu +1

We prove that no nontrivial finite group $G$ satisfies the equivariant generating hypothesis of Bohmann, even when all $R O (H)$ -graded homotopy groups are tested for every subgroup…

A Hurewicz Theorem for $R O (C_{2})$ -graded Equivariant Homology Governed by Vector Fields on Spheres

Manyi Guo, Guchuan Li, Yunze Lu +5

We determine the $R O (C_{2})$ -graded Hurewicz images of the $C_{2}$ -equivariant Eilenberg--MacLane spectra $H F_{2}$ , $H Z$ and $H A$ , whe…

$C_{3}$ -equivariant stable stems

Yueshi Hou, Shangjie Zhang

We compute the spoke-graded $C_{3}$ -equivariant stable homotopy groups of spheres $π_{i, j}^{C_{3}}$ , for stems less than 25 (i.e. $i \leq 25$ ) and for weights between -16 and 16 (i.e.…

Equivariant $v_{1, 0}$ -self maps

William Balderrama, Yueshi Hou, Shangjie Zhang

Let $G$ be a cyclic $p$ -group or generalized quaternion group, $X \in π_{0} S_{G}$ be a virtual $G$ -set, and $V$ be a fixed point free complex $G$ -representation. Under conditions depen…

$C_{p^{n}}$ -equivariant Mahowald invariants

William Balderrama, Yueshi Hou, Shangjie Zhang

The classical Mahowald invariant is an operation that systematically produces new elements in the stable homotopy groups of spheres from known ones. We introduce the $C_{p^{n}}$ -Maho…
