Some New θ-I-Locally Closed sets with Respect to an Ideal Topological Spaces

open access: yesRatio Mathematica, 2023
In this paper, we introduce the new notions called \breve{\mathbit{\theta}}-\mathbf{I}-locally closed sets, \breve{\mathbit{\theta}}-\mathbf{I}-locally closed sets and \breve{\mathbit{\theta}}-\mathbf{I}-closed functions and investigated their properties

Theta Functions on the Theta Divisor

open access: yesRocky Mountain Journal of Mathematics, 2010
We show that the gradient and the hessian of the Riemann theta function in dimension n can be combined to give a theta function of order n+1 and modular weight (n+5)/2 defined on the theta divisor. It can be seen that the zero locus of this theta function essentially gives the ramification locus of the Gauss map.

New proofs for three identities of seventh order mock theta functions

open access: yesAIMS Mathematics, 2023
Using the three-term Weierstrass relation for theta functions and the properties of Hecke-type double sums and Appell-Lerch sums, we give new and simple proofs for the seventh order mock theta conjectures.

Brief Study On A New Family of Analytic Functions [PDF]

open access: yesSahand Communications in Mathematical Analysis
The authors introduced a new class of analytic functions in this study by means of convolution principle and obtain its relations with some well-known subclasses of analytic univalent functions in geometric functions theory in the open unit disk $\mathbb{

ON GENERALIZED EIGHTH ORDER MOCK THETA FUNCTIONS

open access: yesUral Mathematical Journal, 2020
In this paper we have  generalized eighth order mock theta functions, recently introduced by Gordon and MacIntosh involving four independent variables. The idea of generalizing was to have four extra parameters, which on specializing give known functions

Ketamine independently modulated power and phase-coupling of theta oscillations in Sp4 hypomorphic mice. [PDF]

open access: yesPLoS ONE, 2018
Reduced expression of Sp4, the murine homolog of human SP4, a risk gene of multiple psychiatric disorders, led to N-methyl-D-aspartate (NMDA) hypofunction in mice, producing behavioral phenotypes reminiscent of schizophrenia, including hypersensitivity ...

Computing Riemann theta functions [PDF]

open access: yesMathematics of Computation, 2003
The Riemann theta function is a complex-valued function of g complex variables. It appears in the construction of many (quasi-) periodic solutions of various equations of mathematical physics. In this paper, algorithms for its computation are given.

Dimension reduction techniques for the minimization of theta functions on lattices [PDF]

open access: yes, 2016
We consider the minimization of theta functions $\theta_\Lambda(\alpha)=\sum_{p\in\Lambda}e^{-\pi\alpha|p|^2}$ amongst lattices $\Lambda\subset \mathbb R^d$, by reducing the dimension of the problem, following as a motivation the case $d=3$, where ...
