Theorem of the Day 


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. Some general information relating to women in mathematics can be found here. I am unlikely to resume my calendar series "12 Theorems by Women Mathematicians" in the near future (I am only adding new theorems very slowly at present and haven't accumulated enough new ones by women). The 2010 calendar is still available as a free download here.
