摘要：

We prove large deviations principles for spectral measures of perturbed (or spiked) matrix models in the direction of an eigenvector of the perturbation. In each model under study, we provide two approaches, one of which relying on large deviations principle of unperturbed models derived in the previous work "Sum rules via large deviations" (Gamboa et al. [Sum rules via large deviations, J. Funct. Anal. 270(2) (2016) 509-559]).
