A Functional Equation in Arithmetic [PDF]

open access: yesTransactions of the American Mathematical Society, 1936
which occurs in all theories of numerical functions hitherto considered. The two most highly developed theories of this kind are those in which multiplication in the ring of all numerical functions is abstractly identical with C (Cauchy) or D (Dirichlet) multiplication of infinite series.t Lehmer's five postulates are sufficient for the development of ...

A note on $(a,b)$-Fibonacci sequences and specially multiplicative arithmetic functions [PDF]

open access: yesMathematica Bohemica
A specially multiplicative arithmetic function is the Dirichlet convolution of two completely multiplicative arithmetic functions. The aim of this paper is to prove explicitly that two mathematical objects, namely $(a,b)$-Fibonacci sequences and ...

Arithmetic properties of Ramanujan's general partition function for modulo 11

open access: yesKuwait Journal of Science, 2020
In the present work, for the general partition function $p_k(n)$, we establish five new infinite families of congruences. Our emphasis throughout this paper is to exhibit the use of $q$-identities  to generate congruences for the general partition ...

Arithmetic circuit tensor networks, multivariable function representation, and high-dimensional integration

open access: yesPhysical Review Research, 2023
Many computational problems can be formulated in terms of high-dimensional functions. Simple representations of such functions and resulting computations with them typically suffer from the “curse of dimensionality,” an exponential cost dependence on ...

On the Arithmetic of Abelina Functions [PDF]

open access: yesProceedings of the National Academy of Sciences, 1927
Systematic application of abelian functions to the theory of numbers discloses many new arithmetical phenomena of considerable interest. Particularly is this the case when the periods of the functions are connected by one or more singular relations in the usual sense.

Frontal Midline Theta Oscillations during Mental Arithmetic: Effects of Stress

open access: yesFrontiers in Behavioral Neuroscience, 2015
Complex cognitive tasks such as mental arithmetic heavily rely on intact, well-coordinated prefrontal cortex (PFC) function. Converging evidence suggests that frontal midline theta (FMT) oscillations play an important role during the execution of such ...

Bounds for the Neuman–Sándor Mean in Terms of the Arithmetic and Contra-Harmonic Means

open access: yesAxioms, 2022
In this paper, the authors provide several sharp upper and lower bounds for the Neuman–Sándor mean in terms of the arithmetic and contra-harmonic means, and present some new sharp inequalities involving hyperbolic sine function and hyperbolic cosine ...

A unified model for Duchenne muscular dystrophy gene involvement in cancer: context‐dependent tumour suppression and oncogenicity

open access: yesFEBS Open Bio, EarlyView.
We propose a context‐dependent model where the Duchenne muscular dystrophy (DMD) gene acts as a tumour suppressor in aggressive tumours and as an oncogene in less aggressive ones. We propose this model as a unified framework to explain the opposing survival associations with DMD expression and to guide experimental exploration of the dual role of DMD ...

The influence of cardiorespiratory fitness on strategic, behavioral, & electrophysiological indices of arithmetic cognition in preadolescent children

open access: yesFrontiers in Human Neuroscience, 2014
The current study investigated the influence of cardiorespiratory fitness on arithmetic cognition in forty 9-10 year old children. Measures included a standardized mathematics achievement test to assess conceptual and computational knowledge, self ...

Arithmetic Errors in Financial Contexts in Parkinson’s Disease

open access: yesFrontiers in Psychology, 2021
Research on dyscalculia in neurodegenerative diseases is still scarce, despite high impact on patients’ independence and activities of daily living function.
