Péter Maga- Beyond the spherical sup-norm probl...

题目:  Beyond the spherical sup-norm problem 摘要: I will present a power-saving estimate in the restricted sup-norm problem of Maass forms for $\rm{SL}_{2}(\mathbb{Z}[i])$, assuming bounded spectral parameter and increasing dimension of the associated $\rm{SU}_{2}(\mathbb{C})$-type. Joint work with Valent...

马宁—Generalizations of Alladi's formula for a...

题目:  Generalizations of Alladi's formula for arithmetical semigroups 摘要: In this talk, we will discuss a general version of Alladi’s formula with Dirichlet convolution holds for arithmetical semigroups satisfying Axiom A or Axiom A^#.  As applications, we apply our main results to certain semigroups c...

我心中的控制论

题目:  我心中的控制论 摘要:控制广泛存在于人们的实际生活中,切有目的的活动都离不开控制,如卫星控制、火箭控制、飞机控制等。控制论是控制的理论和方法基础,不仅涉及认识世界(系统建模)还涉及改造世界(系统控制),是一个应用面广、交叉性强的学科,充满深刻的挑战性前沿科学问题,是解决众多国家重大需求的必要工具和手段...

齐治-Beyond the Weyl barrier for GL(2) exponent...

题目: Beyond the Weyl barrier for GL(2) exponential sums 摘要: In this talk, I will introduce the Bessel delta-method and two new variants of the van der Corput method in 2 dimensions, and I will explain how to go beyond the Weyl barrier 3/2=1.5 for GL(2) exponential sums up to 1.63651.... This is joint wo...

黄炳荣- On the Rankin-Selberg problem

题目: On the Rankin-Selberg problem 摘要: In this talk, I will sketch two proofs of the classical result of Rankin and Selberg (in 1939/1940) on the second moment of Fourier coefficients of a GL(2) automorphic form. The Rankin-Selberg problem is that whether one can break the 3/5 barrier in this error term...

郗平- Lang-Trotter conjecture for CM elliptic c...

题目:  Lang-Trotter conjecture for CM elliptic curves 摘要: For any elliptic curve $E$ over $\mathbf{Q}$ and any non-zero integer $r$, the Lang-Trotter conjecture has predicted the asymptotic behaviours of the number of good primes $p\leqslant x$, denoted by $\pi_{E,r}(x)$, such that the Frobenius trace of...

高鹏-Bounds for moments of central values of fa...

题目:  Bounds for moments of central values of families of Dirichlet L-functions 摘要: Moments of central values of families of L-functions are important subjects in analytical number theory. In this talk, I will explain two powerful principals in the study of sharp bounds for these moments: the upper boun...

张天平-Mean value of Kloosterman sums

题目:Mean value of Kloosterman sums 摘要:In this talk, I will show possible cancellations on various mean value of Kloosterman sums. Then some interesting applications are displayed. Part of this work is joint with Kui Liu and Igor E. Shparlinski. 报告人:张天平(陕西师范大学) 报告人简介:张天平,陕西师...

吴小胜教授-Some progress on Dirichlet L-functio...

题目:Some progress on Dirichlet L-functions  摘要:In this talk, we will discuss some recent development of Dirichlet L-functions, mainly including the percentage of zeros on the critical line and an asymptotic formula for the fourth moment at the central value.  报告人:吴小胜教授(合肥工业大学) 时间:2...
