Resumen inglés | In this paper we shall compute explicitly the Fourier coefficients of the Eisenstein series Ek,m(z,w) = 1/2 ∑(c,d)=1 (cz + d)-k ∑tÎo exp {2πim((az + b/cz +d)N(t)) + σ(t,(w/cz +d) - (cN(w)/cz + d)} which is a Jacobi form of weight k and index m defined on H1 x CC, the product of the upper half-plane and Cayley numbers over the complex field C. The coefficient of e2πi(nz + σ(t,w)) with nm > N(t) has the form -2(k - 4)/Bk-4 ∏p Sp Here Sp is an elementary factor which depends only on νp(m), νp(t), νp(n) and νp(nm - N(t)) = 0. Also Sp = 1 for almost all p. Indeed, one has Sp = 1 if νp(m) = νp(nm - N(t)) = 0. An explicit formula for Sp will be given in details. In particular, these Fourier coefficients are rational numbers. |
