Computations of Cyclotomic Lattices
We study even modular lattices of leveì and dimension 2(p ? 1), p prime, which arise from the ideal class group of the p-th cyclotomic extension of Q(p ?`). After giving the basic theory we concentrate on Galois-invariant ideals , obtain computational results on minimal vectors and isometries, and identify several old or new extremal lattices.
متن کاملCyclotomic structures on root lattices
The centralizer C(w) of an element w in a Weyl group W plays an important role in the structure and representation theory of split reductive groups G over finite and p-adic fields k, where W is the absolute Weyl group of G. If k is finite, this is well-known: the element w determines a maximal ktorus Tw ⊂ G and C(w) may be identified with the k-rational points in the Weyl group W (Tw, G) of Tw ...
متن کاملCyclotomic Polytopes and Growth Series of Cyclotomic Lattices
The coordination sequence of a lattice L encodes the word-length function with respect toM , a set that generates L as a monoid. We investigate the coordination sequence of the cyclotomic lattice L = Z[ζm], where ζm is a primitive m th root of unity and where M is the set of all m roots of unity. We prove several conjectures by Parker regarding the structure of the rational generating function ...
متن کاملAbout Free Lattices and Free Modular Lattices
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...
