Abstract
The BKP equation is obtained from the reduction of B type in the KP hierarchy
under the orthogonal type transformation group for the KP equation. The skew
Schur Q functions can be used to construct the Tau functions of solitons in the
BKP equation. Then the totally nonnegative Pfaffian can be defined via the skew
Schur Q functions to obtain nonsingular line solitons solution in the BKP
equation. The totally nonnegative Pfaffians are investigated. The line solitons
interact to form web like structure in the near field region and their
resonances appearing in soliton graph could be investigated by the totally
nonnegative Pfaffians.
