Theorems by Women Mathematicians

This separate listing celebrates the women who have proved, or jointly proved, theorems described in this website. Biographical and/or contact details may be found in the Index of Mathematicians. I would be very grateful to hear of any inaccuracies in this information.

Twelve of these theorems have been compiled into a 2009 calendar "12 theorems by women mathematicians" which you can download as pdf files and is available to purchase in spiral-bound A3 form at the Gallery Shop.
