A note on Stormer condition for decomposability of positive maps
W. A. Majewski
TL;DR
This paper explores the Størmer condition, providing a partial characterization of matrices in $M_n( ext{A})^+$ that satisfy this condition, which is relevant for understanding the decomposability of positive maps.
Contribution
It offers a new partial characterization of matrices meeting the Størmer condition, advancing the theoretical understanding of positive map decomposability.
Findings
Identifies specific matrices satisfying the Størmer condition
Provides criteria for decomposability of positive maps
Advances theoretical framework for positive map analysis
