摘要：

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.
