Null boundary controllability for hyperdiffusion equation. (English) Zbl 1177.93018

In this paper we establish null boundary controllability of the hyperdiffusion equation. The problem of null boundary controllability is reduced to a moment problem. The moment problem is solved by using a biorthogonal sequence with respect to real exponential bases. Existence and uniqueness of the specific biorthogonal sequence are proved and it is shown that the biorthogonal sequence has corresponding minimal \(L^2(0,T)\) norm.
