Ahmad ibn Munim
Ahmad ibn Munim , known as Ibn Munim, (* in Dénia ; died 1228 or 1229 in Marrakech ) was an Arabic mathematician. He is known for his early work on combinatorics .
Also Ahmad ibn Ibrahim Abdari, Abū Jaʻfar Aḥmad bin Ibrahīm bin Munʻim al-ʻAbdarī, Ahmed ben Ibrāhīm Ibn Muni'm.
Ibn Munim came from the coastal town of Dénia near Valencia and moved to Marrakech , where he taught mathematics and was widely regarded as the best expert in this field. He started studying medicine at the age of 30 and later practiced as a doctor. He is known for his work Fiqh al-Hisab (Science of Arithmetic). In the 11th chapter he deals with combinatorial problems that came from linguistics (for example the number of permutations of different letters in words of fixed length with and without repetition).
He also wrote treatises on geometry and magic squares, which have not been preserved.
He inspired other mathematicians such as al-Quadi al-Sharif (died 1283), whose work Canon of Computation has not yet been found.
Older literature ( Heinrich Suter , HP-J. Renaud) confused him with Muhammad ibn Abd al-Munim, a mathematician at the court of Roger II in Sicily.
