چکیده
The methods to classify extremal unimodular lattices with given automorphisms are extended the situation of modular lattices. A slightly more general notion than type from PhD thesis [11] is det-type. det-type an automorphism on L determines one all partial dual L. This easy observation allows exclude quite a few det-types left open in [11]. Passing suitable p-maximal lattices, ?-modular composite level ?=14 and ?=15 dimension 12 ones ?=6 16 classified.

This paper deals with the relations between graph automorphisms and direct factors of a semimodular lattice of locally finite length.
متن کاملOn automorphisms of extremal even unimodular lattices
The automorphism groups of the three known extremal even unimodular lattices of dimension 48 and the one of dimension 72 are determined using the classification of finite simple groups. Restrictions on the possible automorphisms of 48-dimensional extremal lattices are obtained. We classify all extremal lattices of dimension 48 having an automorphism of order m with φ(m) > 24. In particular the ...

Ralph Freese Department of Mathematics University of Hawaii at Manoa Honolulu, Hawaii 96822 In this paper we look at some of the problems on free lattices and free modular lattices which are of an order theoretic nature. We review some of the known results, give same new results, and present several open problems. Every countable partially ordered set can be order embedded into a countable free...
متن کاملNearly Modular Orthocomplemented Lattices
Introduction. Let L be a complete, orthocomplemented lattice. We say that L is a dimension lattice if L is weakly modular and there is an equivalence relation on L satisfying the axioms A,B,C, and D' of Loomis [5]. We say that L is locally finite if every element of L is the join of finite elements. If L is a dimension lattice in which every element is finite, then L is modular. Conversely, Kap...
