Operator pencils

The rapid development of internet technology and artificial intelligence drives the demand for flexible sensors. Compared with vacuum technology and solution method, the fabrication of flexible sensors by pencil writing directly has advantages such as low cost, simple operation, low temperature, and no pollution.

In this paper we consider spectral properties of the operator pencils generated by boundary-value problems for second order elliptic equation depending parameter in a plane angle. We receive explicit formula for the eigenvalues and the eigenvectors of the operator pencil, the multiplicity of the eigenvalues, and the differentiability of the eigenvalues and the eigenvectors with respect to the parameter.

In this paper we consider the Sturm-Liouville equations on a finite interval which is fractional-linear in the spectral parameter. The inverse spectral problem consisting of the recovering of the operator from the two spectra is investigated and a uniqueness theorem for solution of the inverse problem is proved.

Variational principles for real eigenvalues of self-adjoint operator pencils in nonseparated root zones are studied. The main concern of this paper is the variational theoryof the spectrum for a class of self-adjoint operator pencils.

This  survey  was  completed  via  the  internet  from  January  7  to  February  20,  2008  by  253  individuals  who  served  on  at  least  one  audit  committee  for  a  publicly  traded  company  in  2007.  Some respondents were also given the option to complete a paper and pencil survey  in  place of the online survey to increase response rate.     While conducting a probability sample with audit committee members is technically possible, it  was not feasible from a cost or time standpoint.

Microsoft@ Excel is a ‘number crunching’ application with the accountant as its primary target. However, it also provides the scientist or engineer with a very powerful computational tool. True, there are more sophisticated mathematical applications, such as Mathematica, MathCAD, Maple, etc., but none are as widely available as Microsoft Excel.
