Description

In this talk, I am going to present the explicit construction of some multi-scalar field theories in
(1 + 1) dimensions supporting BPS solutions. The construction is based on the ideas of the so-called extension method. In particular, I am going to discuss some interesting field theories constructed from non-trivial couplings between several sine-Gordon fields.
