    integral as a formal series of finite dimensional but generally divergent integrals indexed by Feynman graphs the list of which is determined by the Lagrangian of the theory Renormalization is a prescription that allows one to systematically subtract infinities from these divergent terms producing an asymptotic series for quantum correlation functions On the other hand graphs treated as flowcharts also form a combinatorial skeleton of the abstract computation theory and various operadic formalisms in abstract algebra In this role of descriptions of various classes of computable functions such as recursive functions functions computable by a Turing machine with oracles etc graphs can be used to replace standard formalisms having linguistic flavor such as Church s lambda calculus and various programming languages The functions in question are generally not everywhere defined due to potentially infinite loops and or necessity to search in an infinite haystack for a needle which is not there In this paper I argue that such infinities in classical computation theory can be addressed in the same way as Feynman divergences and that meaningful versions of renormalization in this context can be devised Connections with quantum computation are also touched upon 2 Foundations of Mathematics from discrete to continuous and backwards Abstract In this talk the scope of which will be more of a round table contribution I will discuss some historical and philosophical issues related to the continuous discrete dichotomy I will also argue that an emerging shift in foundations is related to homotopy theory and proceeds from the continuous to the discrete rather than in the reverse direction that has dominated the consciousness of working mathematicians for the last century or so Lou Kauffman 1 Topological Quantum Information Theory Abstract This talk is about using topological structures such as unitary representations of the braid group and unitary solutions to the Yang Baxter Equation in studying entanglement quantum computing and quantum algorithms A motivation for this project is the question Is there a relationship betweem topological entanglement linking and knotting and quantum entanglement indecomposable states non locality We will give numerous examples and speculate about the eventual role of topological structures in this aspect of physics and communication 2 Reflexivity Eigenforms Iterants and Discrete Physics Abstract A reflexive domain is a domain D such that there is a 1 1 correspondence between D and the mappings D D from D to D Letting I D D D be this 1 1 correspondence We have the Fixed Point Theorem For any F D D there is an element E of D such that F E E Proof Define Gx F I x x Then G I g for some g in D and so I g x F x x whence I g g F I g g and I g g is the desired fixed point Q E D The reader may note that this arguement is a generalization of Cantor s Diagonal argument so that if we were in a classical logical algebra and F x
