Weyl metrics and Wiener-Hopf factorization
Journal of High Energy Physics, 2020 We consider the Riemann-Hilbert factorization approach to the construction of Weyl metrics in four space-time dimensions. We present, for the first time, a rigorous proof of the remarkable fact that the canonical Wiener-Hopf factorization of a matrix ...

An approach to BPS black hole microstate counting in an N = 2 STU model
Journal of High Energy Physics, 2020 We consider four-dimensional dyonic single-center BPS black holes in the N = 2 STU model of Sen and Vafa. By working in a region of moduli space where the real part of two of the three complex scalars S, T , U are taken to be large, we evaluate the ...

Journal of High Energy Physics, 2022 In this note, we explore holographic attributes of four-dimensional near-extremal Reissner-Nordstrom black hole solutions in ungauged N $$ \mathcal{N} $$ = 2 supergravity theories at the two-derivative level by recasting them as a specific first-order ...

Cascade algorithms for combined acoustic feedback cancelation and noise reduction
EURASIP Journal on Audio, Speech, and Music Processing, 2023 This paper presents three cascade algorithms for combined acoustic feedback cancelation (AFC) and noise reduction (NR) in speech applications. A prediction error method (PEM)-based adaptive feedback cancelation (PEM-based AFC) algorithm is used for the ...

DIFFERENTIABLE DYNAMICAL SYSTEMS [PDF]
Bulletin of the American Mathematical Society, 1967 This is a survey article on the area of global analysis defined by differentiable dynamical systems or equivalently the action (differentiable) of a Lie group G on a manifold M. An action is a homomorphism G→Diff(M) such that the induced map G×M→M is differentiable.
