Abstract
We consider the eigenvalue problem
where Ω ∈ R d is open and bounded, ρ ∈ L∞(Ω) and A ∈ L∞(ΩM d×d ) satisfying
for some α, c > 0.
We show that, under appropriate conditions on smoothness of coefficients, the principal eigenvalue depends continuously on coefficients with respect to Htopology for A and L∞ weak * topology for ρ. An application of this result in optimal shape design problem of optimising the principal eigenvalue is presented.
Moreover, in the same topology for coefficients, we obtain the continuity of corresponding singular values.
