On the derivatives of Hardy's function Z(t) [PDF]

, 2023
Let Z(k)(t) be the k-th derivative of Hardy’s Z-function. The numerics seem to suggest that if k and ℓ have the same parity, then the zeros of Z(k)(t) and Z(ℓ)(t) come in pairs which are very close to each other.

On almost z-supercontinuity

, 2013
Two new classes of functions between topological spaces have been defined recently, and their basic properties have been studied. They are called almost z-supercontinuous functions and almost D-delta-supercontinuous functions.

$\mathcal Z$-distributive function lattices

, 2013
summary:It is known that for a nonempty topological space $X$ and a nonsingleton complete lattice $Y$ endowed with the Scott topology, the partially ordered set $[X,Y]$ of all continuous functions from $X$ into $Y$ is a continuous lattice if and only if ...

FIXED POINT RESULTS FOR (α − β)-ADMISSIBLE ALMOST z-CONTRACTIONS IN METRIC-LIKE SPACE VIA SIMULATION FUNCTION [PDF]

, 2022
In this paper, we establish the existence and uniqueness of a fixed point of (α, β)-admissible almost z-contractions via simulation functions in metric-like spaces.

On Almost Pseudo-Z-symmetric Manifolds [PDF]

On Upper and Lower Z-supercontinuous Multifunctions

, 2005
In this paper, we define a multifunction F : X --> Y to be upper (lower) Z-supercontinuous if F+ (V) (F- (V)) is z-open in X for every open set V of Y.

Almost periodic sequences and functions with given values [PDF]

, 2004
summary:We present a method for constructing almost periodic sequences and functions with values in a metric space. Applying this method, we find almost periodic sequences and functions with prescribed values.

The dust mass function from z ∼0 to z ∼2.5 [PDF]

, 2020
We derive for the first time the dust mass function (DMF) in a wide redshift range, from z ∼ 0.2 up to z ∼ 2.5. In order to trace the dust emission, we start from a far-IR (160-μm) Herschel selected catalogue in the COSMOS field.

Quadratic differentials $(A(z-a)(z-b)/(z-c)^{2}) {\rm d} z^{2}$ and algebraic Cauchy transform [PDF]

, 2016
summary:We discuss the representability almost everywhere (a.e.) in $\mathbb {C}$ of an irreducible algebraic function as the Cauchy transform of a signed measure supported on a finite number of compact semi-analytic curves and a finite number of ...
