Noncommutative scalar solitons: existence and nonexistence.(English)Zbl 0972.81192

Summary: We study the variational equations for solitons in noncommutative scalar field theories in an even number of spatial dimensions. We prove the existence of spherically symmetric solutions for a sufficiently large noncommutativity parameter $$\theta$$ and we prove the absence of spherically symmetric solutions for small $$\theta$$.
