시간:10:45-11:45 " We present some basic constructions and properties in arithmetic Chern– Simons theory … . We construct an arithmetic analogue of Dijkgraaf–Witten TQFT in a certain special situation, namely, we construct arithmetic analogues, for a finite set S of finite primes of a number field k, of the prequantization bundles, the Chern–Simons 1-cocycle, the Chern–Simons functional, the quantum Hilbert space (space of conformal blocks) and the Dijkgraaf–Witten partition function. We show some basic and functorial properties of those arithmetic analogues and gluing formulas for arithmetic Chern–Simons invariants and arithmetic Dijkgraaf–Witten partition functions" Zoom Meeting ID: 830 9045 0287 Passcode: 246638 -서울대 중점연구소 지원
