The analytic continuation of the discrete series. II [PDF]
Transactions of the American Mathematical Society, 1979 This is the second in a series of papers on the analytic continuation of the holomorphic discrete series. In this paper necessary and sufficient conditions for unitarizability are given in the case of line bundles. The foundations for the vector valued case are begun.

ACFlow: An open source toolkit for analytic continuation of quantum Monte Carlo data [PDF]
Computer Physics Communications, 2022 The purpose of analytical continuation is to establish a real frequency spectral representation of single-particle or two-particle correlation function (such as Green's function, self-energy function, and dynamical susceptibilities) from noisy data ...

Tidal response from scattering and the role of analytic continuation [PDF]
Physical Review D, 2021 The tidal response of a compact object is a key gravitational-wave observable encoding information about its interior. This link is subtle due to the nonlinearities of general relativity.

Analytic continuation from limited noisy Matsubara data [PDF]
Journal of Computational Physics, 2022 This note proposes new algorithms for estimating spectral distribution from limited noisy Matsubara data. We consider both the cases of the spectral distribution with a sparse or a continuous support. In both cases, the proposed algorithm first constructs

The Derivation of the Riemann Analytic Continuation Formula from the Euler’s Quadratic Equation
Journal of Nigerian Society of Physical Sciences, 2022 The analysis of the derivation of the Riemann Analytic Continuation Formula from Euler’s Quadratic Equation is presented in this paper. The connections between the roots of Euler’s quadratic equation and the Analytic Continuation Formula of the Riemann ...

Rethinking jets with energy correlators: Tracks, resummation, and analytic continuation [PDF]
Physical Review D, 2020 We introduce an infinite set of jet substructure observables, derived as projections of $N$-point energy correlators, that both are convenient for experimental studies and maintain remarkable analytic properties derived from their representations in ...

Analytic continuation of harmonic sums: Dispersion representation
Nuclear Physics B, 2022 We present a simple representation for analytically continued nested harmonic sums for the arbitrary complex arguments. This representation can be obtained for a wide range of nested harmonic sums from a precomputed database for the pole expressions of ...

Uniformization and Constructive Analytic Continuation of Taylor Series [PDF]
Communications in Mathematical Physics, 2020 We analyze the problem of global reconstruction of functions as accurately as possible, based on partial information in the form of a truncated power series at some point, and additional analyticity properties.

Analytic continuation and reciprocity relation for collinear splitting in QCD * [PDF]
, 2020 It is well-known that direct analytic continuation of DGLAP evolution kernel (splitting functions) from space-like to time-like kinematics breaks down at three loops.
