Multivariate problems occur in many applications. These problems are defined on spaces of $d$-variate functions and $d$ can be huge--in the hundreds or even in
Few books on Ordinary Differential Equations (ODEs) have the elegant geometric insight of this one, which puts emphasis on the qualitative and geometric propert
This book presents the evolution of uniform approximations of continuous functions. Starting from the simple case of a real continuous function defined on a clo
