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 \(\theta\).
