講 題:The local-global principle for multinorm equations

時 間:2020年2月17日 (星期一) 14:00 - 15:00

地 點:臺灣大學天數館

440 室

摘 要:Let k be a global field and L be a finite dimensional 'etale algebra over k.

We consider the norm equation N_{L/k}(x)=c, where c is a nonzero element in k.

Assume that L contains a cyclic extension factor. We give a necessary and sufficient condition for the local-global principle to hold for this norm equation. We will also give several examples in this talk.

茶 會:15:00-16:00

We analyzed the effect of computing a different mean, namely the harmonic mean, of a sequence of Wishart matrices to analyze the high-dimensional structure of the

Tools from computational topology have proven successful in many scientific disciplines, such as fluid dynamics, biology, material science, climatology, etc.. In

In this paper we study the stability question of the inverse bound- ary value problem for the Schr¨odinger equation with a potential and the conductivity equation by partial

In this paper, we would like to derive a quantitative uniqueness estimate, the three-region inequality, for the second order elliptic equation with jump discontinuous coefficients..

To give perspective to put our study, we recall that the unique continuation property may fail for a second order elliptic equation in n ≥ 3 if the leading coefficients are only

In this seminar, I will first give a general introduction to the basics of atomic force microscopy (AFM), and explain how, by using AFM based techniques, we are able to
