On real Waring decompositions of real binary forms
Macarena Ansola, Antonio Díaz-Cano, M. Angeles Zurro
The Waring Problem over polynomial rings asks how to decompose a homogeneous polynomial of degree as a finite sum of -{th} powers of linear forms. In this work we give a…
Factorization of KdV Schrödinger operators using differential subresultants
Juan J. Morales-Ruiz, Sonia L. Rueda, Maria-Angeles Zurro
We address the classical factorization problem of a one dimensional Schrödinger operator , for a stationary potential of the KdV hierarchy but, in this occasio…
Commuting Ordinary Differential Operators and the Dixmier Test
Emma Previato, Sonia L. Rueda, Maria-Angeles Zurro
The Burchnall-Chaundy problem is classical in differential algebra, seeking to describe all commutative subalgebras of a ring of ordinary differential operators whose coefficients…
