Quantum information & computation, 2012
The quantum Fourier transform (QFT) is an important ingredient in various quantum algorithms which achieve superpolynomial speed-ups over classical computers. In this paper we study under which conditions the QFT can be simulated efficiently classically.

MLQ, 2001
The paper gives a new, shorter proof of an important theorem of Richard Kaye: closed normal subgroups of the automorphism group of a countable recursively saturated model of Peano Arithmetic are exactly the pointwise stabilizers of invariant initial segments which are closed under exponentiation [\textit{R.

Groups in which every non-abelian subgroup is self-normalizing
, 2016We study groups having the property that every non-abelian subgroup is equal to its normalizer. This class of groups is closely related to an open problem posed by Berkovich. We give a full classification of finite groups having the above property.

On nilpotent subgroups containing non-trivial normal subgroups
Journal of Group Theory, 2010Let \(G\) be a non-trivial finite group and let \(A\) be a nilpotent subgroup of \(G\). The author proves that if \(|G:A|\leq\exp(A)\), the exponent of \(A\), then \(A\) contains a non-trivial normal subgroup of \(G\). This extends an earlier result by \textit{I. M. Isaacs} [Proc. Am. Math. Soc. 130, No. 7, 1923-1925 (2002; Zbl 0993.20001)], who proved

Normality for elementary subgroup functors
Mathematical Proceedings of the Cambridge Philosophical Society, 1995AbstractWe define a notion of group functor G on categories of graded modules, which unifies previous concepts of a group functor G possessing a notion of elementary subfunctor E. We show under a general condition which is easily checked in practice that the elementary subgroup E(M) of G(M) is normal for all quasi-weak Noetherian objects M in the ...

NORMAL SUBGROUPS OF FUCHSIAN GROUPS
The Quarterly Journal of Mathematics, 1985It is well-known that all finitely-generated Fuchsian groups contain torsion-free normal subgroups of finite index and the particular case of the (2,3,7)-triangle group has been much studied as the corresponding quotient groups are maximal groups of automorphisms of compact Riemann surfaces.

On subgroups containing non-trivial normal subgroups
Israel Journal of Mathematics, 2003We prove that ifA≠1 is a subgroup of a finite groupG and the order of an element in the centralizer ofA inG is strictly larger (larger or equal) than the index [G:A], thenA contains a non-trivial characteristic (normal) subgroup ofG. Consequently, ifA is a stabilizer in a transitive permutation group of degreem>1, thenexp(Z(A))

Groups with Supersoluble Non-normal Subgroups
Algebra Colloquium, 2016The structure of groups in which many subgroups have a certain property χ has been investigated for several choices of the property χ. In particular, groups whose non-normal subgroups are supersoluble are studied in this paper. Moreover, groups with only finitely many normalizers of non-supersoluble groups are considered.
