摘要：

The O(N)-invariant held theory is considered on both an ordinary and a non-commutative sphere (fuzzy sphere). It is shown that in both cases large-N dominant fields (master fields) exist and their explicit forms are presented. They are found to mix the internal symmetry and the (fuzzy) space-time symmetry. It is also argued that the cutoff introduced by the fuzzy sphere plays an essential role in constructing the master field. (C) 1999 Elsevier Science B.V.
