On normal numbers mod 2

Youngho Ahn, Geon Choe (1998)

Colloquium Mathematicae

It is proved that a real-valued function f ( x ) = exp ( π i χ I ( x ) ) , where I is an interval contained in [0,1), is not of the form f ( x ) = q ( 2 x ) ¯ q ( x ) with |q(x)|=1 a.e. if I has dyadic endpoints. A relation of this result to the uniform distribution mod 2 is also shown.

On octahedral extensions of and quadratic -curves

Julio Fernández (2003)

Journal de théorie des nombres de Bordeaux

We give a necessary condition for a surjective representation Gal ( ¯ / ) PGL 2 ( 𝔽 3 ) to arise from the 3 -torsion of a -curve. We pay a special attention to the case of quadratic -curves.

On p 2 -Ranks in the Class Field Tower Problem

Christian Maire, Cam McLeman (2014)

Annales mathématiques Blaise Pascal

Much recent progress in the 2-class field tower problem revolves around demonstrating infinite such towers for fields – in particular, quadratic fields – whose class groups have large 4-ranks. Generalizing to all primes, we use Golod-Safarevic-type inequalities to analyse the source of the p 2 -rank of the class group as a quantity of relevance in the p -class field tower problem. We also make significant partial progress toward demonstrating that all real quadratic number fields whose class groups...
