Full flexibility of the Monge-Ampère system in codimension $d_{*} - d + 1$

Wentao Cao, Jonas Hirsch, Dominik Inauen +1

We prove that $C^{1, α}$ solutions to the Monge-Ampère system in dimension $d$ and codimension $k = d_{*} - d + 1$ , where $d_{*}$ denotes the Janet dimension, are dense in the spac…

Isometric Immersions and Weak Solutions to the Darboux Equation

Wentao Cao, Jonas Hirsch, Dominik Inauen

We study the Darboux equation, a fundamental PDE arising in the theory of isometric immersions of two-dimensional Riemannian manifolds into $R^{3}$ , in the low-regularity re…

The Monge-Ampère system in dimension two is fully flexible in codimension two

Dominik Inauen, Marta Lewicka

We prove that every $C^{1} (ω ˉ)$ -regular subsolution of the Monge-Ampère system posed on a $2$ -dimensional domain $ω$ and with target codimension $2$ , can be uniformly ap…

A Nash-Kuiper theorem for isometric immersions beyond Borisov's exponent

Wentao Cao, Jonas Hirsch, Dominik Inauen

Given any short immersion from an $n$ -dimensional bounded and simply connected domain into $R^{n + 1}$ and any Hölder exponent $α < (1 + n^{2} - n)^{- 1}$ , we construct a $C^{1, α}$ …

The Monge-Ampere system in dimension two and codimension three

Dominik Inauen, Marta Lewicka

We revisit the convex integration constructions for the Monge-Ampère system and prove its flexibility in dimension $d = 2$ and codimension $k = 3$ , up to $C^{1, 1 - 1/ 5}$ …

$C^{1, α}$ Isometric Embeddings of Polar Caps

Camillo De Lellis, Dominik Inauen

We study isometric embeddings of $C^{2}$ Riemannian manifolds in the Euclidean space and we establish that the Hölder space $C^{1, \frac{1}{2}}$ is critical in a suitable sense: in pa…
