Oscillation numbers for continuous Lagrangian paths and Maslov index

  title={Oscillation numbers for continuous Lagrangian paths and Maslov index},
  author={Julia Elyseeva and Peter vSepitka and Roman vSimon Hilscher},
In this paper we present the theory of oscillation numbers and dual oscillation numbers for continuous Lagrangian paths in R. Our main results include a connection of the oscillation numbers of the given Lagrangian path with the Lidskii angles of a special symplectic orthogonal matrix. We also present Sturmian type comparison and separation theorems for the difference of the oscillation numbers of two continuous Lagrangian paths. These results, as well as the definition of the oscillation… Expand


Comparative index and Lidskii angles for symplectic matrices
Abstract In this paper we establish a connection between two important concepts from the matrix analysis, which have fundamental applications in the oscillation theory of differential equations.Expand
Lidskii angles and Sturmian theory for linear Hamiltonian systems on compact interval
Abstract In this paper we investigate the Sturmian theory for general (possibly uncontrollable) linear Hamiltonian systems by means of the Lidskii angles, which are associated with a symplecticExpand

A comparative index theory for discrete symplectic systems implemented into the continuous case and generalized reciprocity principles are proved which formulate new sufficient conditions for R(t) concerning preservation of (non)oscillation of the abnormal Hamiltonian systems as t → ∞. Expand

The concept of oscillation numbers is introduced which generalize the notion of proper focal points and proves the oscillation theorem relating the number of finite eigenvalues in the given interval with the values of the oscillations numbers at the end points of this interval. Expand
A Generalized Index Theorem for Monotone Matrix-Valued Functions with Applications to Discrete Oscillation Theory
This paper generalizes the above index theorem to the case when this critical matrix may be varying, but its rank, as well as the rank of some additional matrix, are constant, which includes as a special case the situation when this matrix has a constant image. Expand
Comparative index for solutions of symplectic difference systems
We introduce the comparative index of two conjoined bases of a symplectic difference system, which generalizes difference analogs of canonical systems of differential equations. We consider the mainExpand
Eigenvalue Problems and Oscillation of Linear Hamiltonian Systems
This paper deals with the oscillation behavior of linear Hamiltonian systems and related eigenvalue problems with general, linearly independent self-adjoint boundary conditions. The main new aspectExpand
The Maslov Index in Symplectic Banach Spaces
We consider a curve of Fredholm pairs of Lagrangian subspaces in a xed Banach space with continuously varying weak symplectic structures. Assuming vanishing index, we obtain intrin- sically aExpand
