We see and represent our social environment not as it is, but as we believe it to be. This is the thesis defended in this book, supported by conceptual elements and illustrated by numerous examples drawn from anthropology, developmental psychology, cognitive psychology and social psychology. These examples show that people sharing different beliefs about the same object produce different images of that object (such as drawings or photos), and highlight that such people interpret the same image of this object differently. Finally, they show that, when these people communicate through images, they find it difficult to understand each other. On the basis of these observations, the book proposes a psychosocial theory of the link between beliefs and iconography. This book is mainly intended for students and researchers in the humanities and social sciences, interested in the problematic of images. However, it will also be of interest to communication practitioners and the general public.

In these notes we consider two kinds of nonlinear evolution problems of von Karman type on Euclidean spaces of arbitrary even dimension. Each of these problems consists of a system that results from the coupling of two highly nonlinear partial differential equations, one hyperbolic or parabolic and the other elliptic. These systems take their name from a formal analogy with the von Karman equations in the theory of elasticity in two dimensional space. We establish local (respectively global) results for strong (resp., weak) solutions of these problems and corresponding well-posedness results in the Hadamard sense. Results are found by obtaining regularity estimates on solutions which are limits of a suitable Galerkin approximation scheme. The book is intended as a pedagogical introduction to a number of meaningful application of classical methods in nonlinear Partial Differential Equations of Evolution. The material is self-contained and most proofs are given in full detail. The interested reader will gain a deeper insight into the power of nontrivial a priori estimate methods in the qualitative study of nonlinear differential equations.
