« Spherics » by Menelaus of Alexandria (1st-2nd c. A.D.) is the most
important book ever written on spherical geometry. It is a profound
work. It contains 91 propositions, and some of them are very difficult
to prove. An edition, from Arabic texts (the Greek original does not
survive), is being published now by De Gruyter, in their series Scientia
Graeco-Arabica, No.21. <br><a href="https://www.degruyter.com/view/product/496630" target="_blank">https://www.degruyter.com/<wbr>view/product/496630</a><br>This
publication contains in particular the first English translation of
Menelaus' treatise. In this talk, I will explain some of the major
theorems on spherical geometry contained in this work.<br>------------------------------<wbr>---------------<br><br>幾何学といっても幅の広い分野でありますので専門にとらわれずに<wbr>多くの方に参<br>加していただくことで活発な情報交換の場を提供できることを,<wbr>世話人一同望ん<br>でいます.<br><br>世話人一同:<br>Martin Guest<br>本間泰史<br>細野忍<br>山田澄生</div>
