  • 报告题目: Exponential sum in F_{p}^{d} along spheres
    报告人:孙文博(美国弗吉尼亚理工)

    报告时间:2020/7/31 14:00-15:00

    报告摘要:The estimate of exponential sums is an important tool in the study of harmonic analysis, analytic number theory and dynamical systems. For example, if p(n) is a polynomial, then it is a well known result that the average of e^{2\pi i p(n)} is zero if at least one of the nonconstant coefficient of p is irrational. In this talk, we will discuss about averages of exponential functions of the form e^{2\pi i p(n)}, with p being a polynomial in F_{p}[x_{1},\dots,x_{d}] and n ranging over a shpere in F_{p}^{d}.

    报告题目: Computability of topological pressure on coded shifts 
    报告人:杨云(美国弗吉尼亚理工)

    报告时间:2020/7/31 15:00-16:00

    报告摘要: In this talk, we will develop a general framework to address the computability of the topological pressure for coded shifts. We apply this framework to S-gap shifts, generalized S-gap shifts, Beta shifts, and Alpha-Beta shifts.
