On the spectrum of the magnetohydrodynamic mean-field alpha^2-dynamo operator
Uwe Guenther, Heinz Langer, Christiane Tretter
The existence of magnetohydrodynamic mean-field alpha^2-dynamos with spherically symmetric, isotropic helical turbulence function alpha is related to a non-self-adjoint spectral pr…
