Abstract

In this paper, we defined a new multi-component BKP hierarchy which takes values in a commutative subalgebra of gl(N,C)gl(N,\mathbb C). After this, we give the gauge transformation of this commutative multi-component BKP (CMBKP) hierarchy. Meanwhile we construct a new constrained CMBKP hierarchy which contains some new integrable systems including coupled KdV equations under a certain reduction. After this, the quantum torus symmetry and quantum torus constraint on the tau function of the commutative multi-component BKP hierarchy will be constructed.
