In the 50 years since the disk instability model for outbursts in cataclysmic variables was proposed in 1974, this model has been developed into a natural extension of the "standard disk model", which is steady and has a simplified vertical disk structure, and has had tremendous success in reproducing the time variability of observations. A unified model explaining outbursts in cataclysmic variables and X-ray binaries has been established, which led to significant progress in understanding accretion disks in other systems, such as active galactic nuclei.
However, recent developments in astronomical observations have led to the discovery of a number of phenomena that cannot be explained by the existing models. There is a need to improve the unified model. In this workshop, we will review historical works, share basic physics and the latest research works with participants, identify unsolved problems in this research field and discuss about future works. This workshop will also stimulate communication between researchers in cataclysmic variables and X-ray binaries, with the aim of understanding the accretion physics over the entire disk.
