Asymptotic distribution of negative eigenvalues for two dimensional Pauli operators with nonconstant magnetic fields
Annales de l'Institut Fourier, Tome 48 (1998) no. 2, pp. 479-515.

Cet article étudie le comportement asymptotique des valeurs propres négatives <-λ, quand λ+0, des opérateurs de Pauli avec un potentiel électrique V(x) qui tend vers 0 à l’infini et avec un champ magnétique non constant, qui est supposé borné ou tendant vers 0 à l’infini. Il est montré, en particulier, que N(λ)=(1/2π) V(x)>λ b(x)dx(1+o(1)), quand V(x) diminue plus rapidement que b(x) sous des hypothèses supplémentaires.

This article studies the asymptotic behavior of the number N(λ) of the negative eigenvalues <-λ as λ+0 of the two dimensional Pauli operators with electric potential V(x) decaying at and with nonconstant magnetic field b(x), which is assumed to be bounded or to decay at . In particular, it is shown that N(λ)=(1/2π) V(x)>λ b(x)dx(1+o(1)), when V(x) decays faster than b(x) under some additional conditions.
