Coefficients in powers of the log series
We determine the p-exponent in many of the coefficients in the power series
(log(1+x)/x)^t, where t is any integer. In our proof, we introduce a variant of
multinomial coefficients. We also characterize the power series x/log(1+x) by
certain zero coefficients in its powers.Comment: 8 page
3-primary v1-periodic homotopy groups of E7
We compute the 3-primary v1-periodic homotopy groups of the exceptional Lie
group E7. Now E8 at the primes 3 and 5 is the only compact simple Lie group
whose odd-primary v1-periodic homotopy groups remian to be computed. The main
work is computing the unstable Novikov spectral sequence of \Omega E7/Sp(2).
Showing that this converges to v1-periodic homotopy groups requires recent work
of Bousfield and Bendersky-Thompson.Comment: 51 pages. Submitted to New York Electronic Journal of Mathematic
