Abstract

We study the Bogomol'nyi-Prasad-Sommerfield wall solutions in massive K"ahler nonlinear sigma models on SO(2N)/U(N) and Sp(N)/U(N) in three-dimensional spacetime. We show that SO(2N)/U(N) and Sp(N)/U(N) models have 2^N\ensuremath-1 and 2^N discrete vacua, respectively. We explicitly construct the exact BPS multiwall solutions for N\ensuremath≤3.
