Functorial transfer between relative trace formulas in rank 1

چکیده
According to the Langlands functoriality conjecture, broadened setting of spherical varieties (of which reductive groups are special cases), a map between L -groups should give rise functorial transfer their local and automorphic spectra. The “beyond endoscopy” proposal predicts that this will be realized as comparison limiting forms (relative) trace formulas these spaces. In paper, we establish for identity -groups, affine homogeneous spaces X = H \ G whose dual group is SL 2 or PGL (with split). More precisely, construct operator orbital integrals ( × ) / -relative formula, Kuznetsov formula . Besides -group, another invariant attached certain -value, space test measures enlarged accommodate given -value. explicitly in terms Fourier convolutions, making it suitable global by Poisson summation hence uniform proof, rank 1 , relations periods values -functions.

On Trace Formulas
We review a variety of recently obtained trace formulas for one-and multi-dimensional Schrr odinger operators. Some of the results are extended to Sturm-Liouville and matrix-valued Schrr odinger operators. Furthermore, we recall a set of trace formulas in one, two, and three dimensions related to point interactions as well as a new uniqueness result for three-dimensional Schrr odinger operators...
متن کاملGeometrization of Trace Formulas
Recently, a new approach to functoriality of automorphic representations [L1] has been proposed in [FLN] following earlier work [L2, L3, L4] by Robert Langlands. The idea may be roughly summarized as follows. Let G and H be two reductive algebraic groups over a global field F (which is either a number field or a function field; that is, the field of functions on a smooth projective curve X over...
متن کاملTrace formulas 16
Dynamics is posed in terms of local equations, but the ergodic averages require global information. How can we use a local description of a flow to learn something about the global behavior? We have given a quick sketch of this program in Sections 1.5 and 1.6; now we redo the same material in greater depth. In Chapter 15 we have related global averages to the eigenvalues of appropriate evolutio...
متن کاملAccuracy of Trace Formulas
Using quantum maps we study the accuracy of semiclassical trace formulas. The role of chaos in improving the semiclassical accuracy, in some systems, is demonstrated quantitatively. However, our study of the standard map cautions that this may not be most general. While studying a sawtooth map we demonstrate the rather remarkable fact that at the level of the time one trace even in the presence...
متن کاملSolutions of Functorial and Non-functorial Metric Domain Equations 1
A new method for solving domain equations in categories of metric spaces is studied. The categories CMS and KMS are introduced, having complete and compact metric spaces as objects and-adjoint pairs as arrows. The existence and uniqueness of xed points for certain endofunctors on these categories is established. The classes of complete and compact metric spaces are considered as pseudo-metric s...
