abstract

The concept of $q$-deformation, or ``$q$-analogue'' arises in many areas of mathematics. In algebra and representation theory, it is the origin of quantum groups; $q$-deformations are important for knot invariants, combinatorial enumeration, discrete geometry, analysis, and many other parts of mathematics. In mathematical physics, $q$-deformations are often understood as ``quantizations''. The recently introduced notion of a $q$-deformed real number is based on the geometric idea of invariance by a modular group action. The goal of this lecture is to explain what is a $q$-rational and a $q$-irrational, demonstrate beautiful properties of these objects, and describe their relations to many different areas. We also tried to describe some applications of $q$-numbers.

  1. Coefficients of $q$-real numbers: their combinatorial meaning and growth

    math.CO 2026-08 accept novelty 8.0 of 10

    Every coefficient of every q-real number between 1 and 2 is bounded in absolute value by the corresponding coefficient of the q-deformed golden ratio, resolving the radius-of-convergence conjecture.

  2. Dimers, filters, and $q$-deformed real numbers

    math.PR 2026-07 accept novelty 7.0 of 10

    Every positive real x gets a snake-graph dimer model whose distinguished-edge odds define a new q-deformation [[x]]_q, equal to q[x]_q for rational x.
