On the $X$ -coordinates of Pell equations which are Tribonacci numbers

Florian Luca, Amanda Montejano, Laszlo Szalay +1

For an integer $d \geq 2$ which is not a square, we show that there is at most one value of the positive integer $X$ participating in the Pell equation $X^{2} - d Y^{2} = \pm 1$ which is a T…

Properties of invariant measures in dynamical systems with the shadowing property

Jian Li, Piotr Oprocha

For dynamical systems with the shadowing property, we provide a method of approximation of invariant measures by ergodic measures supported on odometers and their almost 1-1 extens…

Bias Cancellation in One-Determinant Fixed-Node Diffusion Monte Carlo: Insights from Fermionic Occupation Numbers

Matúš Dubecký

Accuracy of the fixed-node diffusion Monte Carlo (FN-DMC) depends on the node location of the best available trial state $Ψ_{T}$ . The practical FN-DMC approaches available for large…

Non-semigroup gradings of associative algebras

Pasha Zusmanovich

It is known that there are Lie algebras with non-semigroup gradings, i.e. such that the binary operation on the grading set is not associative. We provide a similar example in the…

A regular analogue of the Smilansky model: spectral properties

Diana Barseghyan, Pavel Exner

We analyze spectral properties of the operator $H = \frac{\partial ^{2}}{\partial x ^{2}} - \frac{\partial ^{2}}{\partial y ^{2}} + ω^{2} y^{2} - λ y^{2} V (x y)$ in $L^{2} (R^{2})$ , where $ω \neq = 0$ and $V…
