TL;DR: In this paper, a discrete phase-space Gaussian beam summation representation for electromagnetic radiation from a planar source is presented, which is based on the theory of frames and removes the inherent difficulties of the Gabor representation for both monochromatic and ultra wideband (UWB) fields.
Abstract: [1] A discrete phase-space Gaussian beam summation representation for electromagnetic radiation from a planar source is presented. The formulation is based on the theory of frames and removes the inherent difficulties of the Gabor representation for both monochromatic and ultra wideband (UWB) fields. For monochromatic fields the frame-based representation leads to an efficient and flexible discrete Gaussian beam representation with local and stable expansion coefficients. For UWB fields a novel scaling of the frame overcompleteness parameter is introduced, leading to a new expansion that utilizes a discrete frequency-independent set of beams over the entire relevant spectrum. It is demonstrated that the isodiffracting Gaussian beams provide the snuggest frame representation over the entire spectrum. The rules for choosing the “optimal” frame and beam parameters for a given problem are discussed and demonstrated on application examples.

TL;DR: Two variants of the Krivine abstract machine that reduce lambda-terms to full normal form are presented and a proof of their correctness is given by interpreting their behaviour in the λσ-calculus.
Abstract: We present two variants of the Krivine abstract machine that reduce lambda-terms to full normal form. We give a proof of their correctness by interpreting their behaviour in the ? ?-calculus.

TL;DR: This paper defines additional first order invariants, using color information, and shows that the first order is sufficient to make the characterization accurate, and makes the characterization robust enough for affine illumination transformations.

TL;DR: This paper presents the theoretical background for the problem of MMF, its relations with lexicographic optimization as well as a polynomial approach for achieving leximin maximization, and some computational results illustrate the behavior of the obtained solutions and the required CPU time for a range of random and well-dimensioned networks.
