Factoring Groups Efficiently
We give a polynomial time algorithm that computes a decomposition of a finite group G given in the form of its multiplication table. That is, given G, the algorithm outputs two subgroups A and B of G such that G is the direct product of A and B, if such a decomposition exists.
متن کاملFactoring finite abelian groups
It is shown that if in the factorization of a finite cyclic group each factor has either prime power order or order equal to the product of two primes then one factor must be periodic. This is shown to be the best possible result of this type. 2004 Elsevier Inc. All rights reserved.
متن کاملManaging Adoption Barriers in Integrated Banking Services
Service organizations such as retails banks are attempting to increase their customers' lifetime value through the introduction of service innovations such as integrated banking. To date, these efforts have met with mixed success. This research proposes that strategic consideration of barriers to adoption can significantly alter and enhance the effectiveness of segmentation and communication ef...
متن کاملFactoring Tilting Modules for Algebraic Groups
Let G be a semisimple, simply-connected algebraic group over an algebraically closed field of characteristic p > 0. We observe that the tensor product of the Steinberg module with a minuscule module is always indecomposable tilting. Although quite easy to prove, this fact does not seem to have been observed before. It has the following consequence: If p > 2h − 2 and a given tilting module has h...
متن کاملFactoring Elementary p-Groups for p ≤ 7
It is an open problem if an elementary p-group of rank k ≥ 3 does admit full-rank normalized factorization into two of its subsets such that one of the factors has p elements. The paper provides an answer in the p ≤ 7 special case.
