Khai Nguyen, NC State MathematicsCompactness estimate for some nonlinear PDEs

This talk will be devoted to a fundamental question on the com-

pactness of sets of solutions. The key concept in this study is the Kolmogorov

epsilon-entropy which is the logarithm of the minimum number of elements in

an epsilon-covering of a given (totally bounded) set. I will use this concept to

provide a sharp estimate on minimum number of bits needed to represent a en-

tropy solution of general system of hyperbolic conservation laws and a viscosity

solution of Hamilton-Jacobi equations with accuracy epsilon.
