The Convexity

Implicitly present in the geometry of ancient Greece, convexity finds its rigorous formulation in the 19th century in analysis, within the framework of solving inequalities. In all the fields that use it, as soon as the object being manipulated is convex, we observe that everything becomes easy! Subtle geometric properties "leap to the eye" or are easily established. The concept invades many mathematical fields (topology, operations research...) before being used well beyond, as in artificial intelligence, finance or economics.

Not always apparent: mathematics can constitute a reservoir of inspiration for creators and give rise to plays about the lives of famous characters, stagings of abstract concepts or narratives around the teaching of the discipline. One can even find lessons in mathematics in Molière and Ionesco. Maths develop in many theatrical forms: solo performance, show, lecture, participatory theater, clown, mentalism, burlesque show, school performance, story, tale… The enthusiasts of 'transmission differently' are not lacking!
