Keep Algebrica free and independent

Algebrica is an open project built to collect mathematics in one place, with explanations that are rigorous and readable at the same time. Everything published here is free, requires no registration, and carries no advertising, so the reader finds the text and nothing else.

Keeping the project this way has its costs, and the site earns nothing from the traffic it receives. Anyone who would like to support Algebrica can do so by joining one of the founding campaigns, opened periodically, which let a small number of readers fund the project with a donation for the whole duration of the campaign.

Whoever contributes during a campaign becomes a founding supporter, with a permanent place on this page next to a link to a personal website or a social profile. The supporters of the campaign in progress are shown in the sidebar of the site.

Thank you to everyone who helps keep Algebrica open, independent, and growing.

A special thank you goes to those who have donated once or more and asked to remain anonymous. Your support is generous, and the trust it carries will go into making the site better and more widely read.
