Query: Exact Kink Solitons in Skyrme Crystals   We present an explicit integration of the kink soliton equation obtained in a
recent interesting study of the classical Skyrme model where the field
configurations are of a generalized hedgehog form which is of a domain-wall
type. We also show that in such a reduced one-dimensional setting the
first-order and second-order equations are equivalent. Consequently, in such a
context, all finite-energy solitons are BPS type and precisely known.
