# Shannon-McMillan-Breiman Theorem

Does anyone know of an easy proof of Shannon-McMillan-Brieman Theorem? Thanks

Why, do you know an ugly proof? –  Igor Rivin Nov 30 '11 at 14:36
I agree with Igor Rivin's comment: please try to phrase your question in a more useful and less subjective way. –  Pete L. Clark Nov 30 '11 at 17:44

In addition to Igor's answer, there's also:

D. Ornstein and B. Weiss, "The Shannon-McMillan-Breiman theorem for a class of amenable groups", Israel J. Math. 44 (1983), 53-60.

The OP changed the question to "easy" proof, but this still qualifies. –  Igor Rivin Nov 30 '11 at 19:37
Thank you very much Igor! –  Mahsa Allahbakhshi Nov 30 '11 at 19:42
