Lattice of Congruences in Many Sorted Algebra
For simplicity we adopt the following convention: I, X denote sets, M denotes a many sorted set indexed by I, R1 denotes a binary relation on X, and E1, E2, E3 denote equivalence relations of X. We now state the proposition (1) (E1 ⊔ E2) ⊔ E3 = E1 ⊔ (E2 ⊔ E3). Let X be a set and let R be a binary relation on X. The functor EqCl(R) yielding an equivalence relation of X is defined as follows: (De...

For simplicity we follow a convention: Y denotes a set, I denotes a non empty set, M denotes a many sorted set indexed by I, x, y are arbitrary, k denotes a natural number, p denotes a finite sequence, S denotes a non void non empty many sorted signature, and A denotes a non-empty algebra over S. The following proposition is true (1) For every natural number n and for every finite sequence p ho...
