Local and urban squares play a crucial role in the presence and participation of people and in their interaction promotion. Alexander explained the profound geometric relations and discipline in nature, using the concept of life phenomenon theory and living structures. He believes that humans can revive creatures through creating strong centers and an integrated whole. This study selects Avicenna tomb square and center of Aqajani Beig neighborhood, Hamedan. The main research questions include what the role of Alexander's theory of living centers is in promoting the social interaction in local and urban square and which pattern of Alexander's theory mostly affects social interactions in squares and how the individual factors impact social interactions in local and urban squares. Results reveals that patterns of Alexander's theory are efficient in promoting social interactions in local and urban squares. Individual factors are not effective in this regard, but strong centers and urban square contradictions are more effective in resident's social interactions than that of void spaces and strong centers. Architects, planners, and urban designers can apply the results in designing new urban and local squares.

地方和城市广场在人们的参与和参与以及他们的互动促进中起着至关重要的作用。亚历山大使用生命现象理论和生命结构的概念解释了自然界中深厚的几何关系和纪律。他认为，人类可以通过建立强大的中心和整合的整体来复兴生物。本研究选择哈密丹Avicenna墓广场和Aqajani Beig社区的中心。主要的研究问题包括亚历山大的居住中心理论在促进地方和城市广场的社会互动中的作用，以及亚历山大理论的哪种模式在很大程度上影响广场的社会互动，以及个体因素如何影响地方和城市广场的社会互动。 。结果表明，亚历山大 的理论在促进地方和城市广场的社会互动方面非常有效。个体因素在这方面无效，但牢固的中心和城市广场的矛盾在居民的社会互动中比无效的空间和牢固的中心更有效。建筑师，规划师和城市设计师可以将结果应用于设计新的城市和地方广场。
