Nodes on quintic spectrahedra
Taylor Brysiewicz, Khazhgali Kozhasov, Mario Kummer
Abstract
We classify transversal quintic spectrahedra by the location of 20 nodes on the respective real determinantal surface of degree 5. We identify 65 classes of such surfaces and find an explicit representative in each of them.
