Minimal Taylor algebra structural conjecture
Minimal Taylor algebra structural conjecture
Let be a minimal Taylor algebra, meaning a Taylor algebra whose clone is minimal in the sense used by the source, and suppose that is generated by two elements . A ternary absorbing subalgebra is a proper subalgebra with the ternary absorption property denoted by in the source. Minimal Taylor structural conjecture. At least one of the following holds: has a congruence quotient that is an affine algebra of prime order; it has a congruence quotient that is a two-element semilattice; it has a congruence quotient that is a two-element majority algebra; or there are proper ternary absorbing subalgebras such that , , , and . The conjecture is presented as unresolved and would provide a unified structural description.
