T-algebra homomorphisms

Definition

t-algebra homomorphisms are structure-preserving maps between t-algebras that respect the operations defined in these algebras. They generalize the notion of homomorphisms in algebraic structures, ensuring that the relationships and identities inherent in one t-algebra are maintained in another. This concept is crucial for understanding how different algebraic structures interact, especially within the framework of the Eilenberg-Moore category, which connects algebra with category theory through its handling of algebras over a monad.
