Background. The new generalization of the function of complex variable (q-function) is considered, its main properties are investigated. Such distributions have a special place among the special functions due to their widespread use in many areas of applied mathematics. Objective. The aim of the paper is to study the new generalization of the function of complex variable for application in applied sciences. Methods. To obtain scientific results the general methods of the mathematical analysis, and the theory of special functions have been used. Results. The article deals with new generalization of the function of complex variable – q-functions, its main properties are investigated. The theorem on integral representation of q = xk-analytica...
