Abstract:
We introduce the concept of Hamiltonian closure of subalgebras of universal algebras and obtain a series of its properties and the properties of the lattices of Hamiltonian closed subalgebras of universal algebras.
Keywords:subalgebras and congruences of universal algebras, Hamiltonian closure of a subalgebra, lattices of Hamiltonian closed subalgebras, Hamiltonian simple algebras.
