Социальные действия, взаимодействия и отношения

This article continues the theme of formalization and modeling of social activity, interaction, relationships and fields (see: Doktorovich A.B. Basis of Theory of Modeling of Social Communication, Relationships and Fields. Space and Time 2 (2010): 55–65; Idem. Formal Description and Classification of Social Activities, Interaction and Relationships. Space and Time 2 (2011): 48–57). I show the general approach to the definition and formal explanation of social activities, interaction and relationships and give a quality description of them. I analyze different kinds of social activities and their strengths: super weak, weak, medium strength, strong and super strong, as well as the challenges posed by their social relations having in mind they are the fundamental logic-philosophical, sociological and economic terms. The article explores the scale of ranges of social activities, produced by their relations. The theoretical results given in the work can be useful for proceeding towards more profound research of social, economic, political, scientific and other objects, systems and processes as well as social space and its fields. social activities; interaction; relationships; power of social activities and co-activities; social space; social fields
