Announcement of Ibni Oumar Mahamat Saleh Prize

Dear friends,

1) Petition: You (Editor: CAIMS) are one of the 3525 signatories of the petition for “Ibni Oumar Mahamat Saleh ” ( Eight years ago, on February 3, Ibni Oumar Mahamat Saleh was abducted from his home in N’Djamena by armed forces. He died almost certainly soon after. We cannot forget this, we want to know the circumstances of his death, we want justice to be done.

2) Ibni Prize: The three French Mathematical Societies, SFdS, SMAI and SMF have created in 2009 the Prize Ibni Oumar Mahamat Saleh in his memory. It is awarded annually to a young mathematician of Central or West Africa. It funds a scientific visit. The recipients in 2009, 2010, 2011, 2012, 2013 and 2014 were respectively Oumarou Abdou Arbi, from Niger, Amadou Tall, from Senegal, Solyme Abi Mawaki Sanou, from Togo, El Hadji Deme, from Senegal, Khoffi Wilfrid Houedanou, from Togo and David Jaures Fotsa Mbogne from Cameroon.

The recipient of the 2015 Prize is announced today .
There were twelve candidates. After evaluation of their applications, the Ibni Prize Committee decided unanimously to propose to give the Prize to Valaire Yatat Djeumen. Valaire Yatat Djeumen, a native from Cameroon, is a PhD student at the University of Yaounde 1. His thesis, which develops mathematical models of ecosystems, is jointly directed by Jean Jules Tewa, of Ecole Nationale Supérieure Polytechnique of Yaoundé and by Yves Dumont, of CIRAD in Montpellier, France. It will enable him to make a three-months visit to the research institute CIRAD in Montpellier, in the framework of his PhD.

The subscription for the Prize “Ibni Oumar Mahamat Saleh” can be found at . Your contribution, whatever it is, is very precious. The Ibni Prize also receives the support of CIMPA (Centre International de Mathematiques Pures et Appliquees) and CDC-IMU (Committee for Developing Countries of the International Mathematical Union).

3) The remembrance of Ibni is maintained through posts on the internet. You can check for example Images des Mathématiques Charles Boubel, « Ibni Oumar Mahamat Saleh, « disparu » il y a sept ans » — Images des Mathématiques, CNRS, 2014, which is the last one which appeared. Do not hesitate to post more.

We do not forget Ibni Oumar Mahamat Saleh and we keep asking for the truth on his behalf to the Chadian President Idriss Deby and the French President Francois Hollande.

On this anniversary, we share the grief of Ibni’s family and their need for truth and justice.

2) Prix Ibni: Les trois societes de mathematiques francaises, SFdS, SMAI et SMF ont cree en 2009 un prix Ibni Oumar Mahamat Saleh, a sa memoire. Il est attribue tous les ans a un jeune mathematicien ou une jeune mathematicienne d’Afrique Centrale ou d’Afrique de l’Ouest et finance un sejour scientifique de quelques mois. Les laureats 2009, 2010, 2011, 2012, 2013 et 2014 etaient Oumarou Abdou Arbi, nigerien, Amadou Tall, senegalais, Solym Mawaki Sanou Abi, togolais, El Hadji Deme, senegalais, Koffi Wilfrid Houedanou, togolais et David Jaures Fotsa Mbogne, camerounais.

Le laureat 2015 a ete proclame aujourd’hui .
Le nombre de candidatures soumises a été de 12. Après évaluation des dossiers, le Comité du Prix Ibni a décidé à la majorité de proposer que le Prix soit attribué a Monsieur Valaire Yatat Djeumen. Valaire Yatat Djeumen est un doctorant camerounais, dont la thèse porte sur la modélisation de systèmes écologiques. Ses travaux de recherche sont menés sous l’encadrement conjoint de Jean Jules Tewa, Professeur  à l’Ecole Nationale Supérieure Polytechnique de Yaoundé et d’ Yves Dumont, Directeur de Recherche dans l’UMR AMAP (Botanique et modélisation de l’architecture des plantes et des végétations) à Montpellier. Il effectuera grâce au Prix Ibni un séjour de recherche de trois mois en 2016 qui lui permettra de terminer la redaction de sa these.

La souscription pour le financement du Prix Ibni se trouve a Toute contribution de votre part, meme minine est tres precieuse. Le Prix Ibni est egalement soutenu par le CIMPA (Centre International de Mathematiques Pures et Appliquees) et l’IMU CDC (Comite pour les pays en developpement de l’Union Mathematique Internationale)

3) Le souvenir d’Ibni est aussi maintenu grace aux billets postes sur internet. Vous pouvez consulter par exemple Images des Mathematiques Charles Boubel, « Ibni Oumar Mahamat Saleh, « disparu » il y a sept ans »  Images des Mathematiques, CNRS, 2014 qui est le dernier paru….. N’hesitez pas a en poster d’autres.

Nous n’oublions pas Ibni Oumar Mahamat Saleh et nous continuons a demander la verite a son sujet au president tchadien Idriss Deby et au president francais Francois Hollande. Nous partagerons en cet anniversaire la douleur de la famille d’Ibni Oumar Mahamat Saleh et leur exigence de verite.
