This book is devoted to the fundamentals of general urban development theory. It introduces the concept of the city's "framework," substantiates the principles of cyclical development and the evolutionary dynamics of urban planning systems, summarizes the experience of studying the city in urban planning and related scientific disciplines, and presents theoretical hypotheses. The strength of this text, written by a professional architect, lies not only in its professional quality but also in its new level of understanding of the city and the distribution of people within it, opening up a wide range of humanitarian and research questions.
