Maximal Regularity for Degenerate Evolution Equations with an Exponential Weight Function

2007
In this contribution we consider degenerate evolution equations on the real line that have the distinguished feature that they contain an exponential weight function in front of the time derivative.

Unitary rational best approximations to the exponential function

arXiv.org, 2023
Rational best approximations (in a Chebyshev sense) to real functions are characterized by an equioscillating approximation error. Similar results do not hold true for rational best approximations to complex functions in general.

Exponential mixing for a class of dissipative PDEs with bounded degenerate noise

Geometric and Functional Analysis, 2018
We study a class of discrete-time random dynamical systems with compact phase space. Assuming that the deterministic counterpart of the system in question possesses a dissipation property, its linearisation is approximately controllable, and the driving ...

Exponential estimates for oscillatory integrals with degenerate phase functions

Nonlinearity, 2008
In this paper we give precise asymptotic expansions and estimates of the remainder R(λ) for oscillatory integrals with non Morse phase functions, having degeneracies of any order k ≥ 2. We provide an algorithm for writing down explicitly the coefficients of the asymptotic expansion analysing precisely the combinatorial behaviour of the coefficients ...

Exponential Ergodicity of Stochastic Heat Equations with Hölder Coefficients

SIAM Journal on Mathematical Analysis, 2022
We investigate the stochastic heat equation driven by space-time white noise defined on an abstract Hilbert space, assuming that the drift and diffusion coefficients are both merely H\"older continuous. Random field SPDEs are covered as special examples.
