Starting From the First Non-trivial Eigenvalue
陳木法院士北京師範大學 下午 3:00–4:30 Tòa nhà Hồng Kinh 107 室摘要：
The spectral theory is used in many branches of mathematics, the first eigenvalue is the leading term of the spectrum and so plays an important role in theorist research and practical applications. Some of our results on the first (nontrivial) eigenvalue and some powerful mathematical tools are introduced in the talk.
