Abstract |
|
|
| Let (Pv)(t) = −r2(t)A(t)v′
(t)
′
be a degenerate non-selfadjoint differential operator defined on the ℓ−dimensional
Hilbert space Hℓ = L2(0,1)ℓ, where ¶ (0,1) ∈CĄ, r(t) ∈C1(0,1) and A(t) is a (ℓ×ℓ)−matrix function. In this paper, we will compute
the spectral featurs of the operator P in different cases. |
