Projective Joint Spectra and Characters of representations of $A ~_{n}$

T. Peebles, M. Stessin

For a tuple of square complex-valued $N \times N$ matrices $A_{1}, \dots, A_{n}$ the determinant of their linear combination $x_{1} A_{1} + \dots + x_{n} A_{n}$ , which is called \textit{a pencil}, is…

Spectral surfaces for operator pairs and Hadamard matrices of F type

T. Peebles, M. Stessin

It is well-known that, in general, an appearance of an algebraic hypersurface of finite multiplicity in the projective joint spectrum of an operator tuple does not imply the existe…
