Spectral shorted matrices
Given a n × n positive semidefinite matrix A and a subspace script S sign of ℂn, ∑(script S sign, A) denotes the shorted matrix of A to script S sign. We consider the notion of spectral shorted matrix ρ(script S sign, A) = limm→∞ ∑(script S sign, Am)1/m. Wecompletely characterize this martix in term...
