Strong and full dualisability: three-element unary algebras
| ||
| ||
| Abstract | ||
| We characterise the strongly dualisable
three-element unary algebras and show that every
fully dualisable three-element unary algebra is
strongly dualisable. It follows from the
characterisation that, for dualisable
three-element unary algebras, strong
dualisability is equivalent to a weak form of
injectivity.
