Abstract:
We present a numerical algorithm for computing rigorous upper and lower estimates of the principal eigenvalue of the p-Laplacian.
To control all possible errors including the rounding errors of the
computer arithmetic, we use the interval arithmetic.
We implement our algorithm in the Julia programming language using
IntervalArithmetic.jl package [12].
