A mirror deformation of Markov numbers

Léa Bittmann, Perrine Jouteur, Ezgi Kantarcı Oğuz +2

We introduce a deformed squared Markov equation given by $X^{2} + Y^{2} + Z^{2} + (q + q^{- 1}) (X Y + Y Z + X Z) = 3 (1 + q + q^{- 1}) X Y Z$ . Symmetric solutions of this new equation present a remarka…

Infinite friezes of affine type D

Karin Baur, Léa Bittmann, Emily Gunawan +2

In this article, we study infinite friezes arising from cluster categories of affine type $D$ and determine the growth coefficients for these friezes. We prove that for each affine…
