چکیده انگلیسی
Let f(x)=Ax+b and g(x)=Cx+d be two affine operators given by n-by-n matrices A and C and vectors b and d over a field F. They are said to be biregularly conjugate if f=h-1gh for some bijection h:FnâFn being biregular, this means that the coordinate functions of h and h-1 are polynomials. Over an algebraically closed field of characteristic 0, we obtain necessary and sufficient conditions of biregular conjugacy of affine operators and give a canonical form of an affine operator up to biregular conjugacy. These results for bijective affine operators were obtained by Blanc [Conjugacy classes of affine automorphisms of Kn and linear automorphisms of Pn in the Cremona groups, Manuscripta Math. 119 (2006) 225-241].
