Bounds and extremal domains for Robin eigenvalues with negative boundary parameter

Pedro R. S. Antunes, Pedro Freitas, David Krejcirik

We present some new bounds for the first Robin eigenvalue with a negative boundary parameter. These include the constant volume problem, where the bounds are based on the shrinking…
