Criterion of $p$ -criticality for one term $2 n$ -order difference operators

Petr Hasil (2011)

Archivum Mathematicum

Similarity:

We investigate the criticality of the one term $2 n$ -order difference operators $l {(y)}_{k} = Δ^{n} (r_{k} Δ^{n} y_{k})$ . We explicitly determine the recessive and the dominant system of solutions of the equation $l {(y)}_{k} = 0$ . Using their structure we prove a criticality criterion.

Control Systems on the Orthogonal Group SO(4)

Ross M. Adams, Rory Biggs, Claudiu C. Remsing (2013)

Communications in Mathematics

Similarity:

We classify the left-invariant control affine systems evolving on the orthogonal group $S O (4)$ . The equivalence relation under consideration is detached feedback equivalence. Each possible number of inputs is considered; both the homogeneous and inhomogeneous systems are covered. A complete list of class representatives is identified and controllability of each representative system is determined.

On some formula in connected cocommutative Hopf algebras over a field of characteristic 0

Piotr Wiśniewski (2000)

Colloquium Mathematicae

Similarity:

Let H be a cocommutative connected Hopf algebra, where K is a field of characteristic zero. Let $H^{+} = K e r$ and $h^{+} = h - (h)$ for $h \in H$ . We prove that $d_{h} = \sum_{r = 1}^{\infty} ({(- 1)}^{r + 1} / r) \sum h_{1}^{+} . . . h_{r}^{+}$ is primitive, where $\sum h_{1} \otimes . . . \otimes h_{r} = Δ_{r - 1} (h)$ .

Journal de Théorie des Nombres de Bordeaux

Similarity:

We prove that, for all integers $k$ exceeding some effectively computable number $K$ , the distance from ${(3 / 2)}^{k}$ to the nearest integer is greater than $0 . 5803^{k}$ .
