HOPF ALGEBRA OF PROJECTION FUNCTIONSZarko Mijajlovic, Aleksandar PejovicState University of Novi Pazar, Novi Pazar, Serbia; Institute of Mathematics, Serbian Academy of Science and Arts, Belgrade, SerbiaAbstract: We study Hopf algebras over projection functions of the complex vector $C^X$ appropriate for computing inversion formulas from discrete mathematics. Using calculus of projection functions introduced in this way, we derived various inversion formulas, including Gould's inversion formula and its generalizations. Keywords: Hopf algebra; projection; inverse formula Classification (MSC2000): 03B35; 03C13; 03G27 Full text of the article: (for faster download, first choose a mirror)
