Spectral inequalities for magnetic Neumann Laplacian on rectangles
Tuyen Vu
We consider the magnetic Neumann Laplacian on rectangles, subject to non-homogeneous fields. We prove that the square is a local minimiser of the lowest eigenvalue among all rectan…

Spectral inequality for Dirac right triangles
Tuyen Vu
We consider the Dirac operator on right triangles, subject to infinite-mass boundary conditions. We conjecture that the lowest positive eigenvalue is minimised by the isosceles rig…

Reverse isoperimetric inequality for the lowest Robin eigenvalue of a triangle
David Krejcirik, Vladimir Lotoreichik, Tuyen Vu
We consider the Laplace operator on a triangle, subject to attractive Robin boundary conditions. We prove that the equilateral triangle is a local maximiser of the lowest eigenvalu…
