Non-Commutative (NC) field theories have turned into a hotbed of research activity after its connection to low energy string physics was elucidated by Seiberg and Witten [1, 2]. would like to point out that since solitons are already present in the CP 1 model at θ = 0 (i.e. ordinary spacetime), unlike the noncommutative solitons of the scalar theory [6] it is natural Let us digress briefly on the BPS solitons of CP(1) model in ordinary spacetime. θαβ{Fαµ((Dβφ)†Dµφ + (Dµφ)†Dβφ) − to the ordinary spacetime and its associated dynamical variables and the effects of noncommutativity appears only as additional interaction terms in the action. because as soon as we apply the Seiberg-Witten Map to the ∗-gauge invariant constraint term, Fµν = −i[(Dµφ)†Dνφ − (Dνφ)†Dµφ] = −i[(∂µφ)†∂νφ − (∂νφ)†∂µφ]. model in ordinary spacetime and rewrite the static energy functional in the following form,	./cache/work_p6wwluz325chblqhyrunch453q.pdf	./txt/work_p6wwluz325chblqhyrunch453q.txt
