WebJan 14, 2024 · Hilbert himself unearthed a particularly remarkable connection by applying geometry to the problem. By the time he enumerated his problems in 1900, … Hilbert stated his nineteenth problem as a regularity problem for a class of elliptic partial differential equation with analytic coefficients, therefore the first efforts of the researchers who sought to solve it were directed to study the regularity of classical solutions for equations belonging to this class. See more Hilbert's nineteenth problem is one of the 23 Hilbert problems, set out in a list compiled in 1900 by David Hilbert. It asks whether the solutions of regular problems in the calculus of variations are always analytic. … See more The key theorem proved by De Giorgi is an a priori estimate stating that if u is a solution of a suitable linear second order strictly elliptic PDE of the form $${\displaystyle D_{i}(a^{ij}(x)\,D_{j}u)=0}$$ and See more Nash gave a continuity estimate for solutions of the parabolic equation $${\displaystyle D_{i}(a^{ij}(x)D_{j}u)=D_{t}(u)}$$ where u is a bounded function of x1,...,xn, t defined for t ≥ 0. From his estimate Nash was able to deduce … See more The origins of the problem Eine der begrifflich merkwürdigsten Thatsachen in den Elementen der Theorie der analytischen Funktionen erblicke ich darin, daß es Partielle Differentialgleichungen giebt, deren Integrale sämtlich … See more Hilbert's problem asks whether the minimizers $${\displaystyle w}$$ of an energy functional such as $${\displaystyle \int _{U}L(Dw)\,\mathrm {d} x}$$ are analytic.
