# An algorithmic search for $\mathcal{A}$-annihilated classes in the Dyer-Lashof algebra and $H_*QS^0$ I. Closed form for low lengths and tables in low dimensions

## TL;DR

This paper presents computational results and tables of $\\mathcal{A}$-annihilated monomials in the Dyer-Lashof algebra and $H_*QS^0$, up to dimension 131072, aiming to aid research on spherical classes and hit problems.

## Contribution

It provides the first extensive tables of $\\mathcal{A}$-annihilated classes in these algebraic structures, based on a new algorithm for such computations.

## Key findings

- Tables of $\\mathcal{A}$-annihilated monomials up to dimension 131072.
- Identification of patterns and distributions in $\\mathcal{A}$-annihilated classes.
- Potential for future algorithms to extend these results further.

## Abstract

The aim of this work is to publicise some computational results involving tables which contain $\mathcal{A}$-annihilated monomials, excluding square classes, in the Dyer-Lashof algebra and $H_*QS^0$; our computations go up to dimension $1.1\times 10^7$ but the tables in this paper only announce results up to dimension $2^{17}=131072$ and full tables would be available upon request. The theoretical background for our computations is provided by work of Curtis \cite{Curtis} and Wellington \cite{Wellington} on the $\mathcal{A}$-module structure of the Dyer-Lashof algebra as well as $H_*QS^0$. It seems to us that there is a workable algorithm to do these computations which we plan to announce in a future work, partly to avoid making this paper longer than it is. We hope to receive feedback from the experts on these computations and make our algorithm available as soon as we can. We hope that these tables provide a source for researchers in the field, as well as a pool of data to analyse the behaviour of these sequences, their distributions and other asymptotic behaviours. The problem of computing spherical classes in $H_*QS^0$ as well as the symmetric and non-symmetric hit problems have been our main motivations to pursue this project.
