The textbook "Autosolitons" focuses on a novel area of nonlinear physics that deals with solitary intrinsic states, also known as autosolitons. These phenomena occur in a variety of physical, chemical, and biological dissipative systems and are often observed as highly nonequilibrium regions in slightly nonequilibrium systems. The authors develop an innovative approach to studying self-organization and turbulence, viewing these phenomena as a result of the spontaneous formation and subsequent evolution of autosolitons. The book provides a comprehensive summary of the theory of autosolitons, which has been researched by the authors over many years, and is divided into three largely autonomous parts that address different aspects of the physical nature and experimental studies of autosolitons.
