On finite critical lattices. II
O. E. Perminova Ural Federal University
Abstract:
Critical lattices are considered, i.e., lattices without nontrivial endomorphisms and not containing nontrivial proper sublattices without nontrivial endomorphisms. It is proved that there exist $n$-element critical lattices for $n=7$ and $n\geq9$.
Keywords:
lattice, sublattice, endomorphism, critical lattice.
