Almost all arXiv submitters (and certainly any serious one in a category like this paper's math.AP (Mathematics / Analysis of Partial Differential Equations) <https://arxiv.org/list/math.AP/new https://arxiv.org/list/math.AP/new>; click the "other" in "[pdf, ps, other]" and there click Download sources) will supply the preprint's sources, which in mathematics-heavy fields are almost always LaTeX. The sources are associated in a predictable way with the abstract page, which is what should practically always be supplied instead of a direct link to a PDF or other final format. In this particular case <https://arxiv.org/format/2205.14808 https://arxiv.org/format/2205.14808> lets you "Download source", where the source in question is a tar file with four png images and a large .tex file. The .tex file has long swathes of English text; equations are mostly in $math$, although there are some parts that are likely to be less straightforward to access (e.g. under "Definition of the Ricci and curvature coefficients"). arXiv admins and most authors will react supportively to contact from blind and visually impaired people who want to read a preprint. Some categories and broader disciplines have more work to do than others. For example <https://astrobites.org/2022/07/17/making-astronomy-accessible-for-blind-and-visually-impaired-astronomers/ https://astrobites.org/2022/07/17/making-astronomy-accessibl...> I think should link to the abstract page <https://arxiv.org/abs/2206.13815v1 https://arxiv.org/abs/2206.13815v1> so that one can find the .tex file (and a .docx), but instead directly links to the PDF.
