Type (II) regions between curves of the Fucik spectrum
Nonlinear Differential Equations and Applications, 1997The Fucik spectrum arises in the study of semilinear elliptic boundary value problems of the form (1) \(Au=f(x,u)\), where \(A\) is a selfadjoint operator having compact resolvent on \(L^2(\Omega)\), \(\Omega\subset \mathbb{R}^n\), and \(f(x,t)\) is a Carathéodory function on \(\overline\Omega \times\mathbb{R}\) such that \(f(x,t)/t\to a\) a.e.

Asymptotic behavior of the curves in the Fučík spectrum
Communications in Contemporary Mathematics, 2016In this work, we study the asymptotic behavior of the curves of the Fučík spectrum for weighted second-order linear ordinary differential equations. We prove a Weyl type asymptotic behavior of the hyperbolic type curves in the spectrum in terms of some integrals of the weights.

On the Spectrum of Curve Singularities
1998There is the following crucial problem in the singularity theory: how can we recognize that a singular germ is hypersurface, or complete intersection singularity. Or: is there any criterion which distinguishes the isolated hypersurface singularities among the isolated singularities?

On the electronic spectrum in curved graphene nanoribbons
JETP Letters, 2013Using the formalism of the Dirac equation for curved space-time in the Friedmann model of a non-stationary universe, we calculate the electronic spectrum and density of states in curved graphene nanoribbons. Based on the obtained density of states we further study the current-voltage characteristics of the nanoribbonmetal tunnel junction.

On the Differential Form Spectrum of Negatively Curved Riemannian Manifolds
American Journal of Mathematics, 1984Let M be a complete Riemannian manifold of dimension n. Suppose that the sectional curvatures K of M are negative and pinched by \(-1\leq K\leq - 1+\epsilon\), \(0\leq\epsilon
