Double coverings for quadratic extensions and function fields
, 2009 A double covering of a Galois extension K/k in the sense of P. Das (2000) [4] is an extension K˜/K of degree ⩽2 such that K˜/k is Galois. In this paper we determine explicitly all double coverings of any quadratic extensions, the Carlitz cyclotomic ...

STBC from field extensions of the rational field
, 2002 The construction of space time block code (STBCS) over symmetric m-PSK (m-arbitrary) signal sets for a restricted set of number of antennas n is presented by Sethuraman and Sundar Rajan (see ICC 2002, New York, 2002), using cyclotomic field extensions of

Projective extensions of fields
, 2006 Every field K admits proper projective extensions, that is, Galois extensions where the Galois group is a non-trivial projective group, unless K is separably closed or K is a Pythagorean formally real field without cyclic extensions of odd degree.

Thesis (PhD)--Stellenbosch University, 2024.In this thesis, we gain a deeper understanding of cyclotomic extensions of degree powers of 2 and the classification of radical extensions (both separable and insepa‑ rable) up to isomorphism.

Cyclotomic Units and Class Groups in Z_p-extensions of real abelian number fields
, 2009 International audienceFor a real abelian number field F and for a prime p we study the relation between the p-parts of the class groups and of the quotients of global units modulo cyclotomic units along the cyclotomic Z_p-extension of F.

Magnetic Pentagonal Ring - Galois Extensions and Crystallography
, 2017 The Galois symmetry of exact Bethe Ansatz eigenstates for magnetic pentagonal ring is shown to bear a close analogy to some crystallographic constructions.

Automorphism groups of Wada dessins and Wilson operations
, 2010 Dessins d'enfants (children's drawings) may be defined as hypermaps, i.e. as bipartite graphs embedded in compact Riemann surfaces. They are very important objects in order to describe the surface of the embedding as an algebraic curve.
