Nilpotent groups with three conjugacy classes of non-normal subgroups
Let $G$ be a finite group and $nu(G)$ denote the number of conjugacy classes of non-normal subgroups of $G$. In this paper, all nilpotent groups $G$ with $nu(G)=3$ are classified.
متن کاملcurves with rational subgroups of order three
In this article we present a characterization of elliptic curves defined over a finite field F q which possess a rational subgroup of order three. There are two posible cases depending on the rationality of the points in these groups. We show that for finite fields F q , q ≡ −1 mod 3, all ellip-tic curves with a point of order 3, they have another rational subgroup whose points are not defined ...
متن کاملMaximal Algebraic Subgroups of the Cremona Group of Three Variables Imprimitive Algebraic Subgroups of Exceptional Type
Enriques and Fano [4], [5] classified all the maximal connected algebraic subgroups of Cr3. Our aim is to give modern and rigorous proofs to their results. In [10], we studied the primitive subgroups. In this paper, we deal with exceptional imprimitive groups. The imprimitivity is an analytic notion. The natural translation of the imprimitivity in algebraic geometry is the de Jonquieres type op...

متن کاملAn analysis of three depth recovery techniques
Three depth recovery methods are presented. The methods are based on focusing, zooming, and motion stereo, using a single camera. An introduction to the individual methods is given, followed by an analysis of the error functions. The analysis is used to determine whether the methods are applicable for integration into a single system, enabling recovery of exible and robust depth estimates. Expe...
