**Titre:** The Dynamics of Ocean Waves

**Résumé:** Many aspects of mathematical analysis were originally motivated by the study of fluid dynamics; in particular, waves and currents in bodies of water. I will discuss how mathematical analysis combined with asymptotic theory and accurate numerical simulations contributes, in turn, to a better understanding of the dynamics of ocean waves both at the surface of the ocean and in its interior, in regular situations and in extreme events.

**Titre:** The projective plane and its relation to perspective drawings

**Résumé:** During the Renaissance artists figured out the visual principles of central perspective where two parallel lines seem to meet at infinity. Later mathematicians constructed the projective plane \(\mathbb P^2\) and higher projective spaces \(\mathbb P^n\). We will define the projective plane, explore some of its properties, and consider applications to perspective drawings. As an examples we will study one-point and two-point perspective, and also look at anamorphic art and cubism.
