\n\n\nTitle: Tamagawa Numbers of Linear Algebraic Groups IIAbstract: In th
is second talk\, I plan to take a tour through several topics related to t
he results on Tamagawa numbers presented in the first talk: (1) Tate Duali
ty in Positive Dimension: this is a generalization of classical Tate duali
ty from the case of finite Galois modules to all affine commutative group
schemes of finite type over local and global fields\, and it plays a cruci
al role in understanding Tamagawa numbers of commutative groups\, which in
turn play a central role in understanding Tamagawa numbers of more genera
l groups. (2) Tamagawa numbers of exotic pseudo-reductive groups: these ar
e very special pseudo-reductive groups that only show up in characteristic
s 2 and 3. Computing their Tamagawa numbers involves some interesting idea
s that in turn depend upon very beautiful (but not very well-known) result
s on the arithmetic of semisimple groups over global fields. (3) Pathologi
cal behaviors of unipotent groups: time permitting\, we will discuss some
strange behaviors exhibited by unipotent groups over function fields\, esp
ecially their Tamagawa numbers and Tate-Shafarevich sets.\n\n Export\n
