Bethe-sommerfeld Conjecture
We consider Schrödinger operator −∆+V in R (d ≥ 2) with smooth periodic potential V and prove that there are only finitely many gaps in its spectrum. Dedicated to the memory of B.M.Levitan
متن کاملInhomogeneous Bond Percolation on Square, Triangular, and Hexagonal Lattices
The star–triangle transformation is used to obtain an equivalence extending over the set of all (in)homogeneous bond percolation models on the square, triangular, and hexagonal lattices. Amongst the consequences are box-crossing (RSW) inequalities for such models with parameter-values at which the transformation is valid. This is a step towards proving the universality and conformality of these...
متن کاملOn the Bethe-Sommerfeld conjecture for certain periodic Maxwell operators
The Bethe-Sommerfeld conjecture states that the spectrum of the stationary Schrödinger operator with a periodic potential in dimensions higher than 1 has only finitely many gaps. After work done by many authors, it has been proven by now in full generality. Another case of a significant interest, due to its importance for the photonic crystal theory, is of a periodic Maxwell operator, where app...
متن کاملBethe-sommerfeld Conjecture for Periodic Operators with Strong Perturbations
Abstract. We consider a periodic self-adjoint pseudo-differential operatorH = (−∆)m+ B, m > 0, in R which satisfies the following conditions: (i) the symbol of B is smooth in x, and (ii) the perturbation B has order less than 2m. Under these assumptions, we prove that the spectrum of H contains a half-line. This, in particular implies the Bethe-Sommerfeld Conjecture for the Schrödinger operator...
متن کاملOn the Bethe-sommerfeld Conjecture for the Polyharmonic Operator
It is a general property of elliptic differential operators with periodic coefficients, that their spectra are formed by union of closed intervals called spectral bands (see [12], [14]) possibly separated by gaps. One of the challenging questions of the spectral theory of periodic operators is to find out whether or not the number of gaps in the spectrum of a given operator is finite. The state...
