Network theory and small groups
Social Influence Network Theory: A Sociological Examination of Small Group Dynamics by Noah E. FriedkinSocial influence network theory presents a mathematical formalization of the social process of attitude changes that unfolds in a social network of interpersonal influences. This book brings the theory to bear on lines of research in the domain of small group dynamics concerned with changes of group members positions on an issue, including the formation of consensus and of settled disagreement, via endogenous interpersonal influences, in which group members are responding to the displayed positions of the members of the group. Social influence network theory advances a dynamic social cognition mechanism, in which individuals are weighing and combining their own and others positions on an issue in the revision of their own positions. The influence network construct of the theory is the social structure of the endogenous interpersonal influences that are involved in this mechanism. With this theory, the authors seek to lay the foundation for a better formal integration of classical and current lines of work on small groups in psychological and sociological social psychology.
Social Network Analysis Overview

This article describes the network approach to small groups. First, the core constructs that compose social network research are explained. The primary theories that provide the intel- lectual underpinning of the network approach are described, including theories of self-inter- est, theories of social exchange or dependency, theories of mutual or collective interest, cog- nitive theories, and theories of homophily. Highlights of the empirical work examining the internal and external networks of small groups is summarized. Finally, the primary chal- lenges researchers face when applying the network perspective to small groups, and the pri- mary benefits that can accrue to researchers who adopt that perspective, are enumerated.

First, the core constructs that compose social network research are explained. - A social network is a social structure made up of a set of social actors such as individuals or organizations , sets of dyadic ties, and other social interactions between actors. The social network perspective provides a set of methods for analyzing the structure of whole social entities as well as a variety of theories explaining the patterns observed in these structures.
Network theory is the study of graphs as a representation of either symmetric relations or asymmetric relations between discrete objects. Network theory has applications in many disciplines including statistical physics , particle physics , computer science, electrical engineering   , biology ,  economics , finance , operations research , climatology , ecology and sociology. Applications of network theory include logistical networks, the World Wide Web , Internet, gene regulatory networks , metabolic networks, social networks , epistemological networks, etc. Network problems that involve finding an optimal way of doing something are studied under the name combinatorial optimization. In order to break a NP-hard task of network optimization down into subtasks the network is decomposed into relatively independent subnets. The electric power systems analysis could be conducted using network theory from two main points of view:.
