On inversely $\theta$-semi-open and inversely $\theta$-semi-closed functions

open access: yesМатематичні Студії, 2020
In this paper, we introduce the concepts of inversely $\theta$-semi-open and inversely $\theta$-semi-closed functions and obtain their characterizations if it is possible in terms of $\theta$-closure and $\theta$-interior by using sets determined by the ...

New congruences modulo powers of 2 for k-regular overpartition pairs [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics
Let ̄Bₖ(n) denote the number of k regular overpartition pairs where a k-regular overpartition pair of n is a pair of k-regular overpartitions (a,b) in which the sum of all the parts is n.

A developmental examination of medial frontal theta dynamics and inhibitory control

open access: yesNeuroImage, 2022
Medial frontal theta-band oscillations are a robust marker of action-outcome monitoring. In a large developmental sample (n = 432, 9–16 years), we examined whether phase and non-phase locked medial frontal theta power were related to inhibitory control ...

μ-theta functions [PDF]

open access: yesPacific Journal of Mathematics, 1982
Let A be an abelian, nilpotent finite dimensional algebra over R. Let B((.),(.)) be a symmetric, bilinear form on A which satisfies B(xy,w) = B(y,xw). Define ((.))--the scalar log function on A by (DIAGRAM, TABLE OR GRAPHIC OMITTED.PLEASE SEE DAI) It is shown that the Fourier transform of exp2(pi)i(sigma) (x), for (sigma) a rational member is (sigma)('-

A theory of theta functions to the quintic base [PDF]

open access: yes, 2013
Properties of four quintic theta functions are developed in parallel with those of the classical Jacobi null theta functions. The quintic theta functions are shown to satisfy analogues of Jacobi's quartic theta function identity and counterparts of ...

Arithmetic properties for Andrews’ (48,6)- and (48,18)-singular overpartitions

open access: yesOpen Mathematics, 2019
Singular overpartition functions were defined by Andrews. Let Ck,i(n) denote the number of (k, i)-singular overpartitions of n, which counts the number of overpartitions of n in which no part is divisible by k and only parts ±i (mod k) may be overlined ...

Theta function identities involving fourth power [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics
On page 241 of his Second Notebook, Ramanujan recorded one of his theta function identity, which involves the ratio of the fourth power of theta functions with respect to ψ(q). In this article, we give a new proof for this theta function identity.

Developmental Changes in Hippocampal CA1 Single Neuron Firing and Theta Activity during Associative Learning. [PDF]

open access: yesPLoS ONE, 2016
Hippocampal development is thought to play a crucial role in the emergence of many forms of learning and memory, but ontogenetic changes in hippocampal activity during learning have not been examined thoroughly.

Momentum Dependence of the Single-Particle Self-Energy and Fluctuation Spectrum of Slightly Underdoped Bi_2 Sr_2 CaCu_2 O_{8+\delta} from High Resolution Laser ARPES [PDF]

open access: yes, 2010
We deduce the normal state angle-resolved single-particle self-energy $\Sigma(\theta, \omega)$ and the Eliashberg function (i.e., the product of the fluctuation spectrum and its coupling to fermions) $\alpha^2 F(\theta,\omega)$ for the high temperature ...
