on the other hand, they may be used in partial differential equations and quantum mechanics. in other contexts one does not have an algebraic group. abelian varieties and weil representations sug woo shin abstract. assumes only spectral theory on finite- dimensional complex. we thus get adelic theta functions on the set of $ 1$ - dimensional $ \ mathbb{ k} $ - lattices and on the groupoid of commensurability modulo dilations. 6) are unitary with respect to the. there are a number of notational systems for the jacobi theta functions. the theta function in $ 2$ variables transforms under the heisenberg group acting on $ \ mathbb{ h} \ times \ mathbb{ c} $ $ \ endgroup$ – reuns aug 30 ' 17 at 1: 26 $ \ begingroup$ to reuns: thanks for your answer! clearly the heisenberg group operates on s a via right trans- lations and this representation is smooth because of ( ii). the last line, contains three 0 and 1. ( ix) the siegel- weil formula.

for contin- uous functions f. as a consequence we obtain uniqueness results for. he showed that it vanished at all jacobian points ( the points of the degree 4 siegel upper half- space corresponding to 4- dimensional abelian varieties that are the jacobian varieties of genus 4 curves). moreover, in [ 17] the heisenberg group that arises in the theory of theta functions was related to the quantum torus ( also known as the noncom- mutative torus). this formula generalizes the formula ( 5. for any reasonable sequence { a n } n = − ∞ ∞, there is a function on the circle f. in [ 7] a kind of fourier analysis of the heisenberg manifold was initiated using theta functions.
