On spectra and Brown's spectral measures of elements in free products of matrix algebras

Junsheng Fang, Don Hadwin, Xiujuan Ma

We compute spectra and Brown measures of some non self-adjoint operators in $(M_2(\cc), {1/2}Tr)*(M_2(\cc), {1/2}Tr)$, the reduced free product von Neumann algebra of $M_2(\cc)$ wi…
