The Weil Representation
This is my senior honors thesis done in my final year as an undergraduate at Stanford University, under the direction of Professor Akshay Venkatesh. We will construct the Weil representation of SL2(R) through a natural action of the Heisenberg group Heis(R) on the space of square-integrable complex-valued functions L 2(R), together with the celebrated Stone-von Neumann theorem of functional ana...
متن کاملWeil Transfer of Algebraic Cycles
Let L/F be a finite separable field extension of degree n, X a smooth quasi-projective L-scheme, and R(X) the Weil transfer of X with respect to L/F . The map Z 7→ R(Z) of the set of simple cycles Z ⊂ X extends in a natural way to a map Z(X) → Z(R(X)) on the whole group of algebraic cycles Z(X). This map factors through the rational equivalence of cycles and induces this way a map of the Chow g...
متن کاملThe Segal-Shale-Weil (oscillator) representation
The objects called oscillator representations are decades old, originally developed by physicists for their own purposes. For example, [Weyl 1928], [Stone 1930], [vonNeumann 1931]. Detailed study of the infinitedimensional representation theory of small classical groups appeared first in [Wigner 1939], [Bargmann 1947]. A more modern treatment of oscillator representations began with [Shale 1962...
متن کاملThe Weil Representation in Characteristic Two
In this paper we construct a new variant of the Weil representation, associated with a symplectic vector space (V, ω) defined over a finite field of characteristic two. Our variant is a representation ρ : AMp (V ) → GL (H), where the group AMp (V ) is forth cover of a group ASp (V ), which is a nontrivial gluing of the symplectic group Sp (V ) and the dual group V ∗. In particular, the group AS...
متن کاملGeometric Weil representation: local field case
Let k be an algebraically closed field of characteristic > 2, F = k((t)) and G = Sp 2d . In this paper we propose a geometric analog of the Weil representation of the metaplectic group G̃(F ). This is a category of perverse sheaves on some stack, on which G̃(F ) acts by functors. This construction will be used in [5] (and subsequent publications) for the proof of the geometric Langlands functoria...
