The \({\hat{B}}_n^{(1)}\)-hierarchy is constructed from the standard splitting of the affine Kac–Moody algebra \({\hat{B}}_n^{(1)}\), the Drinfeld–Sokolov \({\hat{B}}_n^{(1)}\)–KdV hierarchy is obtained by pushing down the \({\hat{B}}_n^{(1)}\)-flows along certain gauge orbit to a cross section of the gauge action. In this paper, we
-
(1)
use loop group factorization to construct Darboux transforms (DTs) for the \({\hat{B}}_n^{(1)}\)-hierarchy,
-
(2)
give a Permutability formula and scaling transform for these DTs,
-
(3)
use DTs of the \({\hat{B}}_n^{(1)}\)-hierarchy to construct DTs for the \({\hat{B}}_n^{(1)}\)–KdV and the isotropic curve flows of B-type,
-
(4)
give algorithm to construct soliton solutions and write down explicit soliton solutions for the third \({\hat{B}}_1^{(1}\)–KdV, \({\hat{B}}_2^{(1)}\)–KdV flows and isotropic curve flows on \(\mathbb {R} ^{2,1}\) and \(\mathbb {R} ^{3,2}\) of B-type.
