estimates for joint quasimodes of two pseudodifferential operators whose characteristic sets have -th order contact

Madelyne M. Brown, Melissa Tacy

On a smooth, compact, -dimensional Riemannian manifold, we consider functions that are joint quasimodes of two semiclassical pseudodifferential operators and $…

Filament structure of random waves

Melissa Tacy

We investigate the small scale equidistribution properties of random waves in . Numerical evidence suggests that such objects display a fine scale filament structur…

Small scale equidistribution of random waves generated by an unfair coin flip

Miriam Leonhardt, Melissa Tacy

In this paper we study the small scale equidistribution property of random waves whose coefficients are determined by an unfair coin. That is the coefficients take value with…

Stationary phase type estimates for low symbol regularity

Melissa Tacy

The well-known stationary phase formula gives us a way to precisely compute oscillating integrals so long as the symbol is regular enough (in comparison to the large parameter cont…

A note on constructing sharp examples for norms of eigenfunctions and quasimodes near submanifolds

Melissa Tacy

In this note we analyse estimates for Laplacian eigenfunctions and quasimodes and their associated sharp examples. In particular we use previously determined estimates to p…

Comparable upper and lower bounds for boundary values of Neumann eigenfunctions and tight inclusion of eigenvalues

Alex Barnett, Andrew Hassell, Melissa Tacy

For smooth bounded domains in , we prove upper and lower bounds on the boundary data of Neumann eigenfunctions, and prove quasi-orthogonality of this boundary dat…

The quantisation of normal velocity does not concentrate on hypersurfaces

Melissa Tacy

We seek to extend work by Christianson-Hassell-Toth \cite{CHT} on restrictions of Neumann data of Laplacian eigenfunctions to interior hypersurfaces to a general semiclassical sett…
