Indefinite Eigenvalue Problems with Several Singular Points and Turning Points

Mathematische Nachrichten, 2001
The authors' summary: The authors consider a general case of eigenvalue problems with two-point boundary conditions on a finite interval generated by a differential equation with an indefinite weight function which has several zeros and/or poles. As a basic result, the authors derive asymptotic estimates on a special fundamental system of solutions to ...

Preconditioning of Indefinite and Almost Singular Finite Element Elliptic Equations

SIAM Journal on Scientific Computing, 1998
Summary: This paper deals with two ways of solving discretized finite element elliptic equations with indefinite and almost singular matrices. Such problems typically arise when applying the shifted inverse power iteration method to the generalized eigenvalue problem \(A u=\lambda B u\) where \(A\) is defined from some discretized equation by a finite ...

Singular unitary representations and indefinite harmonic theory

2008
Abstract Square-integrable harmonic spaces are defined and studied in a homogeneous indefinite metric setting. In the process, Dolbeault cohomologies are unitarized, and singlar unitary representations are obtained and studied.

The Singular Indefinite Article with Mass Nouns

2008
This talk bears on the occurrence of the singular indefinite article in noun phrases whose head noun may be regarded as 'mass'. This apparently paradoxical combination is illustrated in three languages: French, English and Haitian creole, and compared with the semantic equivalents in Hebrew.
