WebMay 9, 2011 · It is known that Laplacian operators on many fractals have gaps in their spectra. This fact precludes the possibility that a Weyl-type ratio can have a limit and is also a key ingredient in proving that the Fourier series on such fractals can have better convergence results than in the classical setting. In this paper we prove that the existence … WebMar 4, 2024 · In this paper, we prove the generic version of Cantor spectrum property for quasi-periodic Schrödinger operators with finitely smooth and small potentials, and we also show pure point spectrum for a class of multi-frequency \(C^k\) long-range operators on \(\ell ^2({\mathbb Z}^d)\).These results are based on reducibility properties of finitely … WebQuestion: Given two strings X and Y , respectively, of length m and n defined over a set Σ = {a1, a2, · · · , ak} of finitely many symbols, we are interested in computing an optimal (i.e., … dheedhi anti hair fall shampoo review
