About: Parametrix

An Entity of Type: Election, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

In mathematics, and specifically the field of partial differential equations (PDEs), a parametrix is an approximation to a fundamental solution of a PDE, and is essentially an approximate inverse to a differential operator. A parametrix for a differential operator is often easier to construct than a fundamental solution, and for many purposes is almost as good. It is sometimes possible to construct a fundamental solution from a parametrix by iteratively improving it.

Property Value
dbo:abstract
  • Eine Parametrix ist ein Objekt aus dem mathematischen Teilgebiet der Theorie der partiellen Differentialgleichungen. Es findet insbesondere Verwendung in der Theorie der partiellen Differentialgleichungen und ist eine Verallgemeinerung der Fundamentallösung eines Differentialoperators mit konstanten Koeffizienten.
