We investigate comparison and existence results for viscosity solutions of fully nonlinear,
second-order, elliptic, possibly degenerate equations. These results complement those …

This is a tutorial on some of the main ideas in KAM theory. The goal is to present the
background and to explain and compare somewhat informally some of the main methods of …

Representing shapes as level sets of neural networks has been recently proved to be useful
for different shape analysis and reconstruction tasks. So far, such representations were …

We present Pose-NDF, a continuous model for plausible human poses based on neural
distance fields (NDFs). Pose or motion priors are important for generating realistic new …

From its origins in the minimization of integral functionals, the notion of'variations' has
evolved greatly in connection with applications in optimization, equilibrium, and control. It …

This is the revised second edition of our 1982 book with the same title, which presents a
rather comprehensive treatment of static and dynamic noncooperative game theory, with …

Set-Valued Analysis Page 1 5 Set-Valued Analysis Introduction This chapter relates the
notions of mutations with the concept of gmphical derivatives of set-valued maps and more …

The notion of viscosity solutions of scalar fully nonlinear partial differential equations of
second order provides a framework in which startling comparison and uniqueness …

Problems involving Hamilton-Jacobi equations—which we take to be either of the stationary
form $ H (x, u, Du)= 0$ or of the evolution form ${u_ {t}}+ H (x, t, u, Du)= 0$, where $ Du $ is …

A fast marching level set method is presented for monotonically advancing fronts, which
leads to an extremely fast scheme for solving the Eikonal equation. Level set methods are …
