Ll. Chau et al., N-SOLITON-TYPE SOLUTIONS OF SU(2) SELF-DUALITY YANG-MILLS EQUATIONS IN VARIOUS SPACES AND THEIR BACKLUND-TRANSFORMATIONS, Journal of physics. A, mathematical and general, 27(21), 1994, pp. 7131-7138
We show that Getmanov's N-soliton-type solutions in the self-duality Y
ang-Mills (SDYM) equations in the (+---)-signatured M4-space can be de
rived in a unified way similar to that of deriving 't Hooft's instanto
n solutions in the (++++)-signatured E4-space. Further, we show that s
uch N-soliton-type solutions can also be constructed for the SDYM equa
tions in the (+-+-)-signatured real D4-space.
