This paper establishes uniform consistency results for nonparametric kernel density and regression estimators when time series regressors concerned are nonstationary null recurrent Markov chains.

In this paper, we delve into the convergence challenges concerning with the functions g̃ and g̃′ representing as conjugate Fourier series and derived conjugate Fourier series respectively within ...

Composition operators and Dirichlet series are central topics within functional analysis that bridge operator theory, analytic number theory and complex analysis. At their core, composition operators ...
