On the susceptibility function of piecewise expanding interval maps [PDF]

open access: yes, 2007
We study the susceptibility function Psi(z) associated to the perturbation f_t=f+tX of a piecewise expanding interval map f. The analysis is based on a spectral description of transfer operators.

Differentiation of Interval Functions [PDF]

open access: yesProceedings of the American Mathematical Society, 1972
This paper is concerned with differentiation of interval functions appearing in interval analysis. Two definitions of a derivative are given; the first one uses an isometric restricted imbedding of the quasilinear space of intervals on the real line R, and the other definition is independent ofthat imbedding.

Improving Point and Interval Estimates of Monotone Functions by Rearrangement [PDF]

open access: yes, 2008
Suppose that a target function is monotonic, namely, weakly increasing, and an available original estimate of this target function is not weakly increasing.

Zeros of the Hurwitz zeta function in the interval (0,1) [PDF]

open access: yes, 2011
We first give a condition on the parameters $s,w$ under which the Hurwitz zeta function $\zeta(s,w)$ has no zeros and is actually negative. As a corollary we derive that it is nonzero for $w\geq 1$ and $s\in(0,1)$ and, as a particular instance, the known

Some fundamental theorems in the interval-valued functions and time scales [PDF]

open access: yesJournal of Mahani Mathematical Research
This research investigates the topological structure of the space of interval-valued functions equipped with an order relation defined by open balls. The aim is to establish analogues of fundamental theorems in calculus, including Bolzano’s theorem, the ...

Locally finiteness and convolution products in groupoids

open access: yesAIMS Mathematics, 2020
In this paper, we introduce a version of the Moebius function and other special functions on a particular class of intervals for groupoids, and study them to obtain results analogous to those obtained in the usual lattice, combinatorics and number theory
