Coxeter Elements and Periodic Auslander–reiten Quiver
Traditionally, to study a root system R one starts by choosing a set of simple roots Π ⊂ R (or equivalently, polarization of the root system into positive and negative parts) which is then used in all constructions and proofs. To prove that the resulting answers are independent of the choice of simple roots, one uses the fact that any two choices of simple roots are conjugate under the action o...
متن کاملPeriodic GMP Matrices
We recall criteria on the spectrum of Jacobi matrices such that the corresponding isospectral torus consists of periodic operators. Motivated by those known results for Jacobi matrices, we define a new class of operators called GMP matrices. They form a certain Generalization of matrices related to the strong Moment Problem. This class allows us to give a parametrization of almost periodic fini...
متن کاملLimit Periodic Jacobi Matrices with a Singular Continuous Spectrum and the Renormalization of Periodic Matrices
For all hyperbolic polynomials we proved in [11] a Lipschitz estimate of Jacobi matrices built by orthogonalizing polynomials with respect to measures in the orbit of classical Perron-Frobenius-Ruelle operators associated to hyperbolic polynomial dynamics (with real Julia set). Here we prove that for all sufficiently hyperbolic polynomials this estimate becomes exponentially better when the dim...
متن کاملPeriodic and Non-Periodic Band Random Matrices: Structure of Eigenstates
The structure of eigenstates for the ensembles of standard and periodic Band Random Matrices (BRM) is analysed. The main attention is drawn to the scaling properties of the inverse participation ratio and other measures of Iocahzation Iength. Numerical data are compared with analytical results recently derived for standard BRMS of
متن کاملMarchenko-Ostrovski mappings for periodic Jacobi matrices
We consider the 1D periodic Jacobi matrices. The spectrum of this operator is purely absolutely continuous and consists of intervals separated by gaps. We solve the inverse problem (including characterization) in terms of vertical slits on the quasimomentum domain . Furthermore, we obtain a priori two-sided estimates for vertical slits in terms of Jacoby matrices.
