Pythagorean triples in level sets of completely multiplicative functions

Guilherme Azevedo, Joel Moreira

We show that given completely multiplicative functions $f_{1}, \dots, f_{d}$ taking values in the unit circle, there exist Pythagorean triples (i.e., integer solutions to $x^{2} + y^{2} = z^{2}$ )…

Multipliers and Disjointness from Mixing

Sohail Farhangi, Joel Moreira, Rigoberto Zelada

In 2005, Parreau proved that if a measure preserving system is not strongly mixing then it contains a non-trivial factor that is disjoint from every strongly mixing system. Taking…
