Complex Banach spaces with Valdivia dual unit ball
We study the classes of complex Banach spaces with Valdivia dual unit ball. We give complex analogues of several theorems of real spaces. Further we study relationship of these complex Banach spaces with their ...

Four-Dimensional Visual Exploration of the Complex Number Plane
A straight line intersects a circle in two, one, or no real points. In the last case, they have two complex conjugate intersecting points. We present their construction by tracing the circle with all lines. To visualize these points...

Bounds on Complexity when Sorting Reals
We derive the upper bounds on the complexity of the counting sort algorithm applied to reals. We show that the algorithm has a time complexity O(n) for n data items distributed uniformly or exponentially. The proof is based...

Behaviour of rays at interfaces in anisotropic viscoelastic media
is studied using three different approaches: the real elastic ray theory, the real viscoelastic ray theory and the complex ray theory. In solving the complex eikonal equation, the highest accuracy is achieved by t...

Denoising with real and complex wavelets
We present the comparison between Daubechies complex-valued wavelets (DCW) and Daubechies real-valued wavelets (DRW) in denoising application. The discrete dyadic wavelet transform (DWT) with decimation (nonredundant) is used as wel...
