The -vertex cover problem asks, for an input graph , whether contains vertices which intersect every edge in . The problem has been studied extensively both […]

Speaker: Angsheng Li(Beihang University) Time: 14:00-15:00 (Time in Beijing) 18:00-19:00 (Time in Auckland) April 9, 2021 (Friday) Venue: B1-501, Main Building Abstract: Started at Hilbert’s 1900 program of axiomatizing mathematics, in 1930s, mathematicians including Gödel proposed the definition of “proof” and established the subject of mathematical logic, and more importantly, Turing 1936 proposed a mathematical […]

Speaker: Angsheng Li(Beihang University) Time: 11:00-12:00(Time in Beijing) 15:00-16:00(Time in Auckland) April 8, 2021 (Thursday) Venue: Coffee Beanery (宾诺咖啡) Abstract: Shannon 1945 and 1948 started the mathematical studies of cryptography and of communication, respectively. In 1945,Shannon proposed an information theoretical protocol for data security, leading to the mathematical theory of data security. In 1948, Shannon […]
