SIDE15 is a part of the series of conferences Symmetries and Integrability of Difference Equations SIDE (side-conferences.net), the major series of conferences around the world that brings together mathematicians and physicists specialising in integrability and symmetries of discrete and semi-discrete systems. In 2025, SIDE15 will take place in Sirmione (Lake Garda), Italy. The primary topics of the conference include:

• ordinary and partial difference equations, 
• symmetries and reductions,
• orthogonal polynomials and special functions, 
• integrable discrete systems, 
• integrable dynamical mappings, 
• discrete Painlevé equations, 
• singularity confinement, algebraic entropy (growth of complexity), 
• quantum mappings and quantum field theory on the space-time lattice

and related subjects.

Jointly to SIDE15, the organisation of a summer school called ASIDE15 (Abecedarian SIDE) is planned, with the aim to deepen some topics related to the main conference.
