Quantum continuants, quantum rotundus and triangulations of annuli
Ludivine Leclere, Sophie Morier-Genoud
We give enumerative interpretations of the polynomials arising as numerators and denominators of the -deformed rational numbers introduced by Morier-Genoud and Ovsienko. The con…

On radius of convergence of -deformed real numbers
Ludivine Leclere, Sophie Morier-Genoud, Valentin Ovsienko +1
We study analytic properties of ``-deformed real numbers'', a notion recently introduced by two of us. A -deformed positive real number is a power series with integer coeffic…

-deformations of the modular group and of the real quadratic irrational numbers
Ludivine Leclere, Sophie Morier-Genoud
We develop further the theory of -deformations of real numbers introduced by Morier-Genoud and Ovsienko, and focus in particular on the class of real quadratic irrationals. Our…
