Mathematicians crack code for classifying complex operators

Researchers have developed a complete mathematical framework for categorizing higher-weight Hankel forms—abstract operators used in signal processing and quantum mechanics. The breakthrough could simplify how engineers and physicists classify and work with complex systems that process multidimensional data.

Originaltitel: Trace class criteria for bilinear Hankel forms of higher weights

Abstrakt

<p>In this paper we give a complete characterization of higher weight Hankel forms, on the unit ball of C^d, of Schatten-von Neumann class <em>Sp</em>, 1 <em>≤ </em><em>p ≤ ∞</em>. For this purpose we give an atomic decomposition for certain Besovtype spaces. The main result is then obtained by combining the decomposition and our earlier results.</p>
