| dc.description | Field theory on a fuzzy noncommutative sphere can be considered as a particular matrix approximation of field theory on the standard commutative sphere. We investigate from this point of view the scalar $ϕ^4$ theory. We demonstrate that the UV/IR mixing problems of this theory are localized to the tadpole diagrams and can be removed by an appropiate (fuzzy) normal ordering of the $ϕ^4$ vertex. The perturbative expansion of this theory reduces in the commutative limit to that on the commutative sphere. | |
