A generalization of Eichler's trace formula.

Juliusz Brzezinski (1997)

Collectanea Mathematica

Similarity:

Eichler's trace formula for traces of the Brandt-Eichler matrices is proved for arbitrary totally definite orders in central simple algebras of prime index over global fields. A formula for type numbers of such orders is proved as an application.

Primitive substitutive numbers are closed under rational multiplication

Pallavi Ketkar, Luca Q. Zamboni (1998)

Journal de théorie des nombres de Bordeaux

Similarity:

Let M ( r ) denote the set of real numbers α whose base- r digit expansion is ultimately primitive substitutive, i.e., contains a tail which is the image (under a letter to letter morphism) of a fixed point of a primitive substitution. We show that the set M ( r ) is closed under multiplication by rational numbers, but not closed under addition.
