{"title":"Critical Dynamics of Random Surfaces","authors":"Christof Schmidhuber","doi":"arxiv-2409.05547","DOIUrl":"https://doi.org/arxiv-2409.05547","url":null,"abstract":"Conformal field theories with central charge $cle1$ on random surfaces have\u0000been extensively studied in the past. Here, this discussion is extended from\u0000their equilibrium distribution to their critical dynamics. This is motivated by\u0000the conjecture that these models describe the time evolution of certain social\u0000networks that are self-driven to a critical point. The time evolution of the\u0000surface area is identified as a Cox Ingersol Ross process. Planar surfaces\u0000shrink, while higher genus surfaces grow until the cosmological constant stops\u0000their growth. Three different equilibrium states are distingushed, dominated by\u0000(i) small planar surfaces, (ii) large surfaces with high but finite genus, and\u0000(iii) foamy surfaces, whose genus diverges. Time variations of the order\u0000parameter are analyzed and are found to have generalized hyperbolic\u0000distributions. In state (i), those have power law tails with a tail index close\u0000to 4. Analogies between the time evolution of the order parameter and a\u0000multifractal random walk are also pointed out.","PeriodicalId":501139,"journal":{"name":"arXiv - QuantFin - Statistical Finance","volume":"20 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142190911","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
