On $q$-deformed real numbers (1908.04365v3)
Published 12 Aug 2019 in math.QA
Abstract: We associate a formal power series with integer coefficients to a positive real number, we interpret this series as a "$q$-analogue of a real." The construction is based on the notion of $q$-deformed rational number introduced in arXiv:1812.00170. Extending the construction to negative real numbers, we obtain certain Laurent series.
