An electron is represented in Minkowski space as a geometric object that is close to a four-dimensional ball and endowed with a certain structure. Due to the pseudo-cyclidic Minkowski space, such an object is unlimited and combines the electric charge and its electromagnetic field, usually distinguished from each other. The model allows you to calculate the intensity of the electric and magnetic fields during an arbitrary movement of the charge, describes the spin and intrinsic magnetic moment of the electron, and also leads to the values ​ ​ of the fine structure constant and the Lande factor, which differ from their experimental values ​ ​ by relative values ​ of 2 • 10 ^{-7 and 5 • 10 -6 , respectively. The book is intended for researchers and graduate students interested in the problems of particle theory and relativity.}
