Automorphisms of finite p-groups admitting a partition
For a finite p-group P the following three conditions are equivalent: (a) to have a (proper) partition, that is, to be the union of some proper subgroups with trivial pairwise intersections; (b) to have a proper subgroup outside of which all elements have order p; (c) to be a semidirect product P = P1o ⟨φ⟩ where P1 is a subgroup of index p and φ is a splitting automorphism of order p of P1. It ...
متن کاملAutomorphisms and strongly invariant relations
We investigate characterizations of the Galois connection sInv–Aut between sets of finitary relations on a base set A and their automorphisms. In particular, for A = ω1, we construct a set R of relations that is closed under all invariant operations on relations and under arbitrary intersections, but is not closed under sInv Aut.
متن کاملIsomorphism of Quadratic Norm and Pc Ordering of Estimators Admitting
BAN estimators generally admit first order representations which insure them to be also asymptotically Pitman closest. For AN estimators admitting a first order representation, an ordering under the Pitman closeness measure is established and is shown to be isomorphic to the one under 'the usual quadratic norm. Multiparameter problems are also treated in the same vein.
متن کاملOrdering Constraints on Discourse Relations
Recent work investigates the ordering constraints discourse relations impose on texts. Wolf and Gibson (2003) generated GraphBank, a discourse-annotated corpus without a prior constraint to tree-structured annotations, showing that naive annotators generate representations containing multiple-parented nodes and relations with crossing arguments. Webber et al. (2003) hypothesize that discourse m...
متن کاملDeriving Laws from Ordering Relations
The effect of Richard T. Cox’s contribution to probability theory was to generalize Boolean implication among logical statements to degrees of implication, which are manipulated using rules derived from consistency with Boolean algebra. These rules are known as the sum rule, the product rule and Bayes’ Theorem, and the measure resulting from this generalization is probability. In this paper, I ...
