華南農(nóng)業(yè)大學(xué)數(shù)信學(xué)院系列講座
報告人:Paula Cerejeiras教授(阿威羅大學(xué))
題目一: Ternary Grassmann algebras and Fock spaces with a view to hypersymmetry
日期:2024年7月16日
時間:9:30-11:00(北京時間)
地點:數(shù)學(xué)與信息學(xué)院西樓605
摘要: Supersymmetry is based on Z2-graded algebras, of which Clifford and Grassmann algebras are classical examples as they allows us to consider a Fock space of monogenic function and build most of the necessary ingredients for a theory of entire functions. But more general settings (for example, quarks) require a more general type of supersymmetry. In this talk we shall present the groundwork for an Ito;/Malliavin stochastic calculus and a Hida’s white noise analysis in the context of a supersymmetry based on Z3-graded algebras. To this end, we establish a ternary Fock space and the corresponding strong algebra of stochastic distributions and present its application in the study of stochastic processes.
題目二:Pseudo-differential Operator Calculus in Discrete Clifford Analysis
日期:2024年7月16日
時間:11:00-12:30(北京時間)
摘要: In this talk we present discrete pseudo-differential operators in the context of Clifford analysis. We will
establish the necessary calculus which will be used to discuss questions like boundedness and compactness
of operators. In the end, we will discuss well-known examples from Clifford analysis as well as give new
examples including discrete Dirac operators with non-constant coefficients.
