In this paper, we prove that there exists a infinite set of non-trivial local Fitting classes every element in which is decomposable as a non-trivial product of Fitting classes such that every factor in the product is neither local nor a formation. In particular, this gives a positive answer to Problem 11.25 a） in The Kourovka notebook.

In recent years,a wide variety of centralised and decentralised algorithms have been proposed for residential charging of electric vehicles(evs).In this paper,we present a mathematical framework which casts the ev charging scenarios addressed by these algorithms as optimisation problems having either temporal or instantaneous optimisation objectives with respect to the different actors in the power *** this framework and a realistic distribution network simulation testbed,we provide a comparative evaluation of a range of different residential ev charging strategies,highlighting in each case positive and negative characteristics.

The quest for the origin of species has entered the genomics era. Despite decades of evidence confirming the role of the environment in ecological speciation, an understanding of the genomics of ecological speciation is still in its infancy. In this review, we explore the role of genomic architecture in ecological speciation in postglacial fishes. Growing evidence for the num- ber, location, effect size, and interactions among the genes underlying population persistence, adaptive trait divergence, and re- productive isolation in these fishes reinforces the importance of considering genomic architecture in studies of ecological speci- ation. Additionally, these populations likely adapt to new freshwater environments by selection on standing genetic variation, as de novo mutations are unlikely under such recent divergence times. We hypothesize that modular genomic architectures in post- glacial fish taxa may be associated with the probability of population persistence. Empirical studies have confirmed the genic na- ture of ecological speciation, implicating surprisingly extensive linkage disequilibrium across the genome. An understanding of these genomic mosaics and how they contribute to reproductive barriers remains unclear, but migration rates and the strength of selection at these loci is predicted to influence the likelihood of population divergence. Altogether, understanding the role of ge- nomic architecture is an important component of speciation research and postglacial fishes continue to provide excellent organ- isms to test these questions, both from the perspective of variation in architectures among taxa, and with respect to the distinct environments they have colonized. However, more empirical tests of ecological speciation predictions are needed [Current Zoo- logy 59 （1）： 53-71, 2013].
