An extension of the Fiedler-Markham determinant inequality
Ligang Kuai · Linear and Multilinear Algebra · 2017
We extend a determinant inequality of Fiedler and Markham [On a theorem of Everitt, Thompson, and de Pillis, Math Slovaca, 44 (1994), 441–444] to the class of matrices whose numerical range is contained in a sector. Moreover, some related results are also included.
