Accessory parameters are mathematical objects which appear in linear differential equations, unknown functions of differential equations associated to isomonodromic deformation. Moreover, they are related to number theory, algebraic geometry, differential geometry, representation theory and mathematical physics. This workshop is organized for the purpose of exchanging research on accessory parameters and the related topics.
