Strong and full dualisability: three-element unary algebras Academic Article uri icon

abstract

  • AbstractWe 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.
