報告摘要
報告題目: Zeta Functions of p-Adic Analytic Varieties
報告人：萬大慶教授
摘要: We introduce the zeta function of a p-adic analytic variety, which counts Teichmuller rational points. This zeta function has the amazing property of being a rational function, which suggests new avenues for further research. This talk is based on joint work with Wei Cao, and will be essentially self-contained.
報告題目：Fidelity Preserved Data Hiding in Encrypted Images Based on Homomorphism and Matrix Embedding
報告人：廖群英教授
摘要：This talk proposes a data hiding scheme for high quality stego-images in the encrypted images based on a homomorphic encryption algorithm and matrix embedding method. We offer a matrix embedding method using Golay code, which has good embedding efficiency. In the proposed scheme, we pre-code the least significant bit (LSB) vectors of the cover image into the codewords before image encryption, so that we can implement the matrix embedding in the encrypted image. The experimental results show that the proposed scheme has excellent security performance. We can get a high quality stego-image after the image decryption and recover the cover image into a fidelity image while providing considerable payload.
報告題目： Unit roots of the unit root L-functions
報告人：楊麗萍副研究員
摘要：As a consequence of Wan's theorem about Dwork's conjecture, the unit root L-function constructing from an algebraic family of L-funcitons are $p$-adic meromorphic. A natural question is to ask the roots and poles of the unit root L-functions. In this talk, we will introduce some results about the unit roots, which including the work of Haessig and Sperber, and our recent work about the Kloosterman family.

報告題目：New bounds for zeros of complete symmetric polynomials over finite fields
報告人：張俊教授
報告摘要：In this talk, we will introduce the new results on counting zeros of complete symmetric polynomials over finite fields, which greatly improve the previous bounds. This work is joint with Prof. Daqing Wan.
