E. Hitzer: General Two-Sided Clifford Fourier Transform, Convolution and Mustard Convolution


E. Hitzer, General Two-Sided Clifford Fourier Transform, Convolution and Mustard Convolution, submitted to Adv. of Appl. Cliff. Algs, 04 Feb. 2016. Available as preprint: http://vixra.org/abs/1602.0044

Abstract: In this paper we use the general steerable two-sided Clifford Fourier transform (CFT), and relate the classical convolution of Clifford algebra-valued signals over $\R^{p,q}$ with the (equally steerable) Mustard convolution. Continue reading

E. Hitzer: Space-Time Fourier Transform, Convolution and Mustard Convolution


Eckhard Hitzer, Space-Time Fourier Transform, Convolution and Mustard Convolution, 15 Pages. Submitted to S. Bernstein and P. Cerejeiras (eds.), Complex Variables and Elliptic Equations (Taylor & Francis), Special Issue entitled “Clifford analysis – theory and applications”, 26 Jan. 2016. Preprint download: http://vixra.org/pdf/1601.0283v1.pdf

Abstract: In this paper we use the steerable space-time Fourier transform (SFT), and relate the classical convolution of the algebra for space-time $Cl(3,1)$-valued signals over the space-time vector space $\R^{3,1}$, with the (equally steerable) Mustard convolution. Continue reading
