Concentration of Laplace eigenfunctions

, 2012
In this thesis, we give a review of known results concerning the concentration of Laplace eigenfunctions in the high-energy limit. We review asymptotic bounds on Lp norms of eigenfunctions, and possible quantum limits, under a variety of hypotheses on ...

Symmetric polynomials: DIM integrable systems versus twisted Cherednik systems

Physics Letters B
We discuss interrelations between eigenfunctions of the Hamiltonians associated with the commutative (integer ray) subalgebras of the Ding-Iohara-Miki algebra and those of the twisted Cherednik system.

Spectral Properties of the Laplace Operator with Variable Dependent Boundary Conditions in a Disk

Axioms
In this work, we study the spectral properties of the Laplace operator with variable dependent boundary conditions in a disk. The boundary conditions include periodic and antiperiodic boundary conditions as well as the generalized Samarskii–Ionkin-type ...

Exponential decay of two-body eigenfunctions: A review

Electronic Journal of Differential Equations, 2000
We review various results on the exponential decay of the eigenfunctions of two-body Schrödinger operators. The exponential, isotropic bound results of Slaggie and Wichmann for eigenfunctions of Schrödinger operators corresponding to eigenvalues below ...
