Benoit's message has suffered a transmission problem,
Here is a more legible version:
I came across this sequence defined by the recursion:
a(1)=1, a(2)=1, n>=3, a(n)=r*(a(ceil(n/2))-a(floor(n/2))) where r>1.
I'm interested with the asymptotic behaviour of a(n). For instance I guess
u(n)<<n if r=2 and u(n)<<n^(1/2)L(n) if r=3/2 where L is a slowly varying
function. Does anyone know a reference for the general case or confirm this
fact for r=2 and r=3/2?
