Existence of discrete eigenvalues for the Dirichlet Laplacian in a two-dimensional twisted strip

Rafael T. Amorim, Alessandra A. Verri

We study the spectrum of the Dirichlet Laplacian operator in a two-dimensional twisted strip embedded in $R^{d}$ with $d \geq 2$ . It is shown that a local twisting perturbati…

Spectrum of the Dirichlet Laplacian in waveguides with parallel cross-sections

Alessandra A. Verri

Let $Ω \subset R^{3}$ be a waveguide which is obtained by translating a cross-section in a constant direction along an unbounded spatial curve. Consider $- Δ_{Ω}^{D}$ the Dirichlet…
