We characterize the polynomials which are nowhere negative semidefinite on certain `bounded basic closed semialgebraic sets´ of bounded Hilbert space operators. The obtained representation for these polynomials involves multipliers analogous to the representation known from the classical commutative Positivstellensatz. It is still an open problem if a noncommutative version of Hilbert's 17th problem holds.</dcterms:abstract> <dc:creator>Klep, Igor</dc:creator> <dcterms:title>A Nichtnegativstellensatz for polynomials in noncommuting variables</dcterms:title> <dspace:hasBitstream rdf:resource="https://kops.uni-konstanz.de/bitstream/123456789/15642/2/nirgends.pdf"/> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/15642"/> <foaf:homepage rdf:resource="http://localhost:8080/jspui"/> <dcterms:bibliographicCitation>First publ. in: Israel Journal of Mathematics ; 161 (2007), 1. - S. 17-27</dcterms:bibliographicCitation> </rdf:Description> </rdf:RDF>
