Point Spectrum: Linear Hamiltonian Systems,miltonian system, the balance is reflected in the symmetry of the spectrum, which typically pins the essential spectrum to the imaginary axis in unweighted spaces. The mechanism for bifurcation in Hamiltonian systems thus falls upon the point spectrum.

Malleable

The Evans Function for Boundary-Value Problems,ructure, as arises from symmetries (Chapter 4.2) and in Hamiltonian systems (Chapter 7). In this chapter we construct the Evans function, an analytic function of the spectral parameter with the property that its zeros correspond to eigenvalues with the order of the zero equal to the algebraic multiplicity of the eigenvalue.

The hypothesis of magnetic accretion is compared to other explanations, and it seems likely that the intensification of Fraunhofer lines (by factors 10 to a million) is indeed predominantly due to factual high abundances of a few
