Equiconvergence of Spectral Decompositions for Sturm–Liouville Operators: Triples of Lebesgue Spaces
Publikováno v:
Lobachevskii Journal of Mathematics. 42:1027-1052
The paper deals with the Sturm–Liouville operator generated on the finite interval $$[0,\pi]$$ by the differential expression $$-y^{\prime\prime}+q(x)y$$ , where $$q=u^{\prime}$$ , $$u\in L_{\varkappa}[0,\pi]$$ for some $$\varkappa\geq 2$$ , and ar

We consider one-dimensional Dirac operatorLP,U with Birkhoff regular boundary conditions and summable potential P(x) on[0, ]. We introduce strongly and weakly regular operators. In both cases, asymptotic formulas for eigenvalues are found. In these f

Tourism is undoubtedly considered to be a strategic industry, especially in the countries with unique natural, cultural and historical resources. However, not very long ago the function of tourism in Russia was more of social character than of econom

We study the equiconvergence of spectral decompositions for two Sturm–Liouville operators on the interval [0, π] generated by the differential expressions $${{l}_{1}}(y) = - y'' + {{q}_{1}}(x)y$$ and $${{l}_{2}} = - y'' + {{q}_{2}}(x)y$$ and the s

We study the classical problem of equiconvergence of spectral expansions for the Sturm-Liouville operator with a singular potential. We present various conditions on the potential guaranteeing the equiconvergence for the expansions of an arbitrary in

We study one-dimensional Dirac operator L on the segment [0,π] with regular in the sense of Birkhoff boundary conditions U and complex-valued summable potential P=(pij(x)), i,j=1,2. We prove uniform estimates for the Riesz constants of systems of ro
