Linear Algebra and its Applications, 2001 Eigenvalue enclosing of the elliptic operator which is linearized at an exact solution of certain nonlinear elliptic equations is considered. This problem is relevant in the analysis of the stability or bifurcation of some solutions for nonlinear problems. The indices of eigenvalues, especially the first eigenvalue are also investigated.

Maximization problems for eigenvalues of linear elliptic operators
Sibirskie Elektronnye Matematicheskie Izvestiya, 2017 The work discusses the eigenvalue problem for elliptic operators. In particular, it is shown that every solution of the eigenvalue maximization problem corresponds to a saddle point for some functional associated with this problem. The conditions respected to this statement fulfilment are formulated.

Eigenvalue, maximum principle and regularity for fully non linear homogeneous operators
, 2006 The main scope of this article is to define the concept of principal eigenvalue for fully non linear second order operators in bounded domains that are elliptic and homogenous. In particular we prove maximum and comparison principle, Holder and Lipschitz

Eigenvalue Problem Describing Magnetorotational Instability in Outer Regions of Galaxies
MathematicsThe existence of magnetic fields in spiral galaxies is beyond doubt and is confirmed by both observational data and theoretical models. Their generation occurs due to the dynamo mechanism action associated with the properties of turbulence.
