Approximability in the GPAC [PDF]
Logical Methods in Computer Science, 2018 Most of the physical processes arising in nature are modeled by either ordinary or partial differential equations. From the point of view of analog computability, the existence of an effective way to obtain solutions of these systems is essential. A pioneering model of analog computation is the General Purpose Analog Computer (GPAC), introduced by ...

Approximation by repeated Padé approximants
Journal of Computational and Applied Mathematics, 1995 AbstractIt is well known that the nth diagonal Padé approximant (PA) of a Markov-Stieltjes function f converges with geometric rate to f. A special case of what we prove is that if n = 2k the same rate of convergence may be obtained by first constructing the kth diagonal PA p1q1 of f and then the kth diagonal PA of q12f.

Approximation of solutions to multidimensional parabolic equations by approximate approximations
Applied and Computational Harmonic Analysis, 2016 Abstract We propose a fast method for high order approximations of the solution of n -dimensional parabolic problems over hyper-rectangular domains in the framework of the method of approximate approximations. This approach, combined with separated representations, makes our method effective also in very high dimensions.

Approximating Approximate Distance Oracles
, 2016 Given a finite metric space $(V,d)$, an approximate distance oracle is a data structure which, when queried on two points $u,v \in V$, returns an approximation to the the actual distance between $u$ and $v$ which is within some bounded stretch factor of the true distance.

False Approximations of the Approximate Number System?
PLoS ONE, 2011 Prior research suggests that the acuity of the approximate number system (ANS) predicts future mathematical abilities. Modelling the development of the ANS might therefore allow monitoring of children's mathematical skills and instigate educational intervention if necessary.

Population and species neighbor identity impact trait–trait relationships and plant performance
Population Ecology, EarlyView.We evaluated how populations and species identity influence plant performance and trait outcomes in mixtures, and assessed trait variation among populations of two forb species native to the western United States (Dieteria canescens and Heterotheca villosa) following three interaction treatments (single‐population monoculture, two‐population mixture ...

Zeros of Approximate Functional Approximations [PDF]
Mathematics of Computation, 1967 The gN(s) are of interest as approximations to the Riemann zeta function. Let s = or + it. In [1], it was shown that for t sufficiently large, gi(s) and g2(s) have their zeros on the critical line ar = 2. After encountering analytical difficulties in attempting to extend this theorem to further N, the calculations described below were undertaken.

Effects of chronic browsing on life‐history traits of an irruptive large herbivore population
Population Ecology, EarlyView.This study aimed to determine the relationship between diet quality, body mass, and size (hind foot length), and female reproduction and sought to identify the mechanism by which high density under severe food limitations is maintained. Our results demonstrated that sika deer introduced to Nakanoshima Island have maintained high densities through high ...
