摘 要：we show that any nonlinear field theory giving rise to static solutions with finite energy like, e.g., topological solitons, allows us to derive a continuous infinity of integral identities which any such solution has to obey. these integral identities can always be understood as being generated by field transformations and their related noether currents. further, we consider applications of these identities to a broad class of nonlinear scalar theories, including the skyrme model. more concretely, we find nontrivial integral identities that can be seen as model-independent relations between certain physical properties of the solitons in such theories, and we comment on the possible connection between these new relations and those already found in the context of astrophysical compact objects. we also demonstrate the usefulness of said identities to estimate the precision of the numerical calculation of soliton observables.
