We consider not necessarily self-adjoint differential operators generated by ordinary differential expressions of the form My= f: pi(t)y"' on Z=[l, co) (\*) i=O with n = ord(M) E N, pi E ci(Z, C). With A4 + we denote the adjoint expression b!f+y= i (-l)Qi(t)y)(i) i=O and with 7',(M) and T,(M) the mi

It is well known that integers or polynomials can be multiplied in an asymptotically fast way using the discrete Fourier transform. In this paper, we give an analogue of fast Fourier multiplication in the ring of skew polynomials C[x, ฮด], where ฮด = x โ โx . More precisely, we show that the multiplic
Given a squarefree polynomial P โ k 0 [x, y], k 0 a number field, we construct a linear differential operator that allows one to calculate the genus of the complex curve defined by P = 0 (when P is absolutely irreducible), the absolute factorization of P over the algebraic closure of k 0 , and calcu
