An algebraic construction of twin-like models

Understand

If the generalized dynamics of K field theories (i.e., field theories with a non-standard kinetic term) is taken into account, then the possibility of so-called twin-like models opens up, that is, of different field theories which share the same topological defect solution with the same energy density.

• These twin-like models were first introduced in Phys.
