Fourier non-uniqueness sets from totally real number fields

Let K be a totally real number field of degree n >= 2. The inverse different of K gives rise to a lattice in Rn. We prove that the space of Schwartz Fourier eigenfunctions on R-n which vanish on the "component-wise square root" of this lattice, is infinite ...

Topological Structures on DMC spaces

Rajai Nasser

Two channels are said to be equivalent if they are degraded from each other. The space of equivalent channels with input alphabet X and output alphabet Y can be naturally endowed with the quotient of the Euclidean topology by the equivalence relation. We s ...

A Theoretical Investigation of Topological Insulator Nanostructures

Naunidh Singh Virk

The topology of the electron wavefunctions in certain band insulators can give rise to novel topological phases. Materials harbouring such topological phases are termed topological insulators (TI). A gapped bulk electronic spectrum, described by a topologi ...

Introducing the Common Cross Connected Stage (C3S) for the 5L ANPC Multilevel Inverter

Alfred Rufer

This paper proposes a novel multilevel Power Electronics Building Block (PEBB) for the 5 level ANPC multilevel voltage source inverter [7]. The PEBB is composed of 6 switches in a crossed configuration [8] and one capacitor. It is common to the 3 phases of ...
