On the square root of the Laplace--Beltrami operator as a Hamiltonian
Classical and Quantum Gravity, 1994Summary: The Einstein equations for a spacetime of the form \(T^ 2 \times \mathbb{R}\) can be reduced to a Hamiltonian system on the Teichmüller space. However, the resulting Hamiltonian is the square root of the quadratic form in the momenta. Trying to make sense of this as a quantum operator is problematic since the Hamiltonian operator would be non ...

On the Gamma-convergence of Laplace-Beltrami operators in the plane
2000A mapping \(f:\Omega\to\mathbb{R}^2\) from a plane domain has finite distortion if \(f\in W^{1,2}(\Omega)\) and \(|f'(x)|^2\leq K(x) J(x,f)\) a.e.
