Generation of theta activity (RSA) in the cingulate cortex of the rat [PDF]
, 1982 Unit activity recorded from the cingulate cortex during theta rhythm shows periodic trains of spikes which are phase-locked to the local theta field potential waves. These cortical theta units were also shown to be correlated with hippocampal theta units.

Fermions on replica geometries and the $\Theta$ - $\theta$ relation [PDF]
Communications in Number Theory and Physics, 2019 In arXiv:1706:09426 we conjectured and provided evidence for an identity between Siegel $\Theta$-constants for special Riemann surfaces of genus $n$ and products of Jacobi $\theta$-functions. This arises by comparing two different ways of computing the \nth \Renyi entropy of free fermions at finite temperature.

LMS Journal of Computation and Mathematics, 2000 AbstractLong-term solutions of the theta method applied to scalar nonlinear differential equations are studied in this paper. In the case where the equation has a stable steady state, lower bounds on the basin of non-oscillatory, monotonic attraction for the theta method are derived. Spurious period two solutions are then analysed.

Parametric CR-umbilical Locus of Ellipsoids in $\mathbb{C}^2$
, 2017 For every real numbers $a \geqslant 1$, $b \geqslant 1$ with $(a,b) \neq (1,1)$, the curve parametrized by $\theta \in \mathbb{R}$ valued in $\mathbb{C}^2 \cong \mathbb{R}^4$ \[ \gamma\, \colon \ \ \ \theta \,\,\,\longmapsto\,\,\, \big( x(\theta ...

Theta Functions on the Theta Divisor
Rocky 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.

Finitely-Generated Projective Modules over the Theta-deformed 4-sphere
, 2012 We investigate the "theta-deformed spheres" C(S^{3}_{theta}) and C(S^{4}_{theta}), where theta is any real number. We show that all finitely-generated projective modules over C(S^{3}_{theta}) are free, and that C(S^{4}_{theta}) has the cancellation ...

A continuum-tree-valued Markov process [PDF]
, 2012 We present a construction of a L\'evy continuum random tree (CRT) associated with a super-critical continuous state branching process using the so-called exploration process and a Girsanov's theorem.

Discriminants of theta-representations
ANNALI SCUOLA NORMALE SUPERIORE - CLASSE DI SCIENZE, 2023 Tevelev has given a remarkable explicit formula for the discriminant of a complex simple Lie algebra, which can be defined as the equation of the dual hypersurface of the minimal nilpotent orbit, or of the so-called adjoint variety. In this paper we extend this formula to the setting of graded Lie algebras, and express the equation of the corresponding

Rotations and Tangent Processes on Wiener Space
, 2003 The paper considers (a) Representations of measure preserving transformations (``rotations'') on Wiener space, and (b) The stochastic calculus of variations induced by parameterized rotations $\{T_\theta w, 0 \le \theta \le \eps\}$: ``Directional ...

Atmospheric Neutrino Oscillations, theta(13) and Neutrino Mass Hierarchy [PDF]
, 2003 We derive predictions for the Nadir angle (theta(n)) dependence of the ratio N(mu)/N(e) of the rates of the mu-like and e-like multi-GeV events measured in water-Cerenkov detectors in the case of 3-neutrino oscillations of the atmospheric nu(e) (antinu(e)
