Let $r \geq 3$ , $n \geq r$ and $π = (d_{1}, d_{2}, ..., d_{n})$ be a non-increasing sequence of nonnegative integers. If $π$ has a realization $G$ with vertex set $V (G) = {v_{1}, v_{2}, ..., v_{n}}$ such that $d_{G} (v_{i}) = d_{i}$ for $i = 1, 2, ..., n$ and $v_{1} v_{2} \dots v_{r} v_{1}$ is a cycle of length $r$ in $G$ , then $π$ is said to be potentially $C_{r}^{''}$ -graphic. In this paper, we give a characterization for $π$ to be potentially $C_{r}^{''}$ -graphic.

Tight bounds for the dihedral angle sums of a pyramid

Applications of Mathematics

Similarity:

We prove that eight dihedral angles in a pyramid with an arbitrary quadrilateral base always sum up to a number in the interval $(3 π, 5 π)$ . Moreover, for any number in $(3 π, 5 π)$ there exists a pyramid whose dihedral angle sum is equal to this number, which means that the lower and upper bounds are tight. Furthermore, the improved (and tight) upper bound $4 π$ is derived for the class of pyramids with parallelogramic bases. This includes pyramids with rectangular bases, often used in finite element mesh generation...

Two sided norm estimate of the Bergman projection on $L^{p}$ spaces

Czechoslovak Mathematical Journal

Similarity:

We give some explicit values of the constants $C_{1}$ and $C_{2}$ in the inequality $C_{1} / sin (\frac{π}{p}) \leq {|P|}_{p} \leq C_{2} / sin (\frac{π}{p})$ where ${|P|}_{p}$ denotes the norm of the Bergman projection on the $L^{p}$ space.

Dunkl-Gabor transform and time-frequency concentration

Saifallah Ghobber (2015)

Czechoslovak Mathematical Journal

Similarity:

The aim of this paper is to prove two new uncertainty principles for the Dunkl-Gabor transform. The first of these results is a new version of Heisenberg’s uncertainty inequality which states that the Dunkl-Gabor transform of a nonzero function with respect to a nonzero radial window function cannot be time and frequency concentrated around zero. The second result is an analogue of Benedicks’ uncertainty principle which states that the Dunkl-Gabor transform of a nonzero function with...
