Local Spectral Asymptotics for the Dirac Operator with Strong Magnetic Fieldr to those of the previous chapter: sections 7.1–7.4 and sections 7.6–7.8 correspond to sections 6.1–6.4 and sections 6.5–6.7 respectively. However, there appears a new section 7.5 devoted to the case of a very strong magnetic field. Namely, the condition . ≤ const is not natural for the Dirac opera

Estimates of the Negative Spectrumupper estimates for .. (.)) in order to derive upper and lower estimates for .. (.) = .(−∞, .) where .. (.) is the number of negative eigenvalues of the self-adjoint operator . (counting their multiplicities), provided (−∞, 0) does not intersect the essential spectrum of A and N. (.) = ∞ otherwise.

Weylian Asymptotics of Spectramptotics. In sections 10.2–10.4 we consider asymptotics of eigenvalues tending to infinity: in section 10.2 the domain is bounded “in principal” (i.e., exits to infinity are thin enough) and the coefficients are weakly singular; in section 10.3 the coefficients are strongly singular and the coercivi

Asymptotics of the Spectra of Schrödinger and Dirac Operators with Strong Magnetic Fieldagnetic field is important. We saw in Chapters 6 and 7 that these four operators are essentially different. Moreover, it is convenient to separate the case of constant spectral parameter τ from the case in which τ tends to some specific limit τ* in a given situation. Therefore this chapter is divide

Miscellaneous Asymptotics section 12.1 I treat operators in domains with “thick” cusps, in section 12.2 I consider operators with potentials degenerate at infinity (such as the Schrödinger operator with a positively homogeneous potential .. ≥ 0 with thick cusp {.. ≤ .} for any fixed . > 0); section 12.3 is devoted to maxima
