Convexity of level lines of Martin functions and applications

A. -K. Gallagher, J. Lebl, K. Ramachandran

Let $Ω$ be an unbounded domain in $R \times R^{d} .$ A positive harmonic function $u$ on $Ω$ that vanishes on the boundary of $Ω$ is called a Martin function. In thi…

On Lewy extension for smooth hypersurfaces in $C^{n} \times R$

Jiri Lebl, Alan Noell, Sivaguru Ravisankar

We prove an analogue of the Lewy extension theorem for a real dimension $2 n$ smooth submanifold $M \subset C^{n} \times R$ , $n \geq 2$ . A theorem of Hill and Tai…

Unentangled Measurements and Frame Functions

Jiri Lebl, Asif Shakeel, Nolan Wallach

Gleason's theorem asserts the equivalence of von Neumann's density operator formalism of quantum mechanics and frame functions, which are functions on the pure states that sum to 1…
