Quantum Super Theta Vectors and Theta Functions

open access: yesKyungpook mathematical journal, 2016
\textit{Y. Manin}'s constructions of quantum theta function and quantum theta vector [Lett. Math. Phys. 56, 295--320 (2001; Zbl 1081.14501)] are extended to the super tori. Classically, theta functions play the role of observables and states. However, in quantum mechanics, the roles of observables and states separated.

Computational models of O-LM cells are recruited by low or high theta frequency inputs depending on h-channel distributions

open access: yeseLife, 2017
Although biophysical details of inhibitory neurons are becoming known, it is challenging to map these details onto function. Oriens-lacunosum/moleculare (O-LM) cells are inhibitory cells in the hippocampus that gate information flow, firing while phase ...

A role for preparatory midfrontal theta in autism as revealed by a high executive load brain–computer interface reverse spelling task

open access: yesScientific Reports
Midfrontal theta oscillations have been linked to executive function, yet their role in autism—where this function is often compromised—remains unclear.

Mock Theta Functions

open access: yes, 2002
The mock theta functions were invented by the Indian mathematician Srinivasa Ramanujan, who lived from 1887 until 1920. He discovered them shortly before his death. In this dissertation, I consider several of the examples that Ramanujan gave of mock theta functions, and relate them to real-analytic modular forms of weight 1/2.

Theta Functions and Szeg�� Kernels

open access: yes, 2002
We study relations between two fundamental constructions associated to vector bundles on a smooth complex projective curve: the theta function (a section of a line bundle on the moduli space of vector bundles) and the Szeg kernel (a section of a vector bundle on the square of the curve). Two types of relations are demonstrated.

Postoperative loss of perineuronal nets in the hippocampal CA1 region results in memory consolidation deficits

open access: yesBrain Research Bulletin
Postoperative cognitive dysfunction (POCD) is a common postoperative neurological complication, with memory consolidation deficits being one of its prominent features.

Theta Functions on Noncommutative Tori

open access: yesLetters in Mathematical Physics, 2001
Ordinary theta-functions can be considered as holomorphic sections of line bundles over tori. We show that one can define generalized theta-functions as holomorphic elements of projective modules over noncommutative tori (theta-vectors). The theory of these new objects is not only more general, but also much simpler than the theory of ordinary theta ...

Explicitp-adic theta functions

open access: yesInventiones Mathematicae, 1986
Let \(k\) be an algebraically closed field of characteristic \(p>2\); let \(W(k)\) be the ring of Witt vectors over \(k\). Let \(B\) be a \(W(k)\)-algebra. \(B\) is said to be \(p\)-adic provided it is closed and separated in the \(p\)-adic topology.

On a Double Series Representation of $\pi$

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2016
This paper proposes a new representation of $\pi$ as a double series. This representation follows from the relation between the Weierstrass $\wp$-function and the Jacobi theta-function.
