Probab.}, fjournal = {Electronic Communications in Probability}, volume = {17}, year = {2012}, keywords = {Large deviations; Coulomb gas; Random matrices; Compactification}, abstract = {We investigate a Coulomb gas in a potential satisfying a weaker growth assumption than usual and establish a large deviation principle for its empirical measure. As a consequence the empirical measure is seen to converge towards a non-random limiting measure, characterized by a variational principle from logarithmic potential theory, which may not have compact support. The proof of the large deviation upper bound is based on a compactification procedure which may be of help for further large deviation principles.
