### "Equation"

<t>Let’s add to the confusion: We are looking for the solution of eq x^x^x…= n.Let’s call (in the spirit of a previous comment, no offences to the actual professions)1. “physicist solution” : n must be in the domain (0,e] (because is working!), then sqrt(2) is a solution for n=22. “econometrician so...

### "Equation"

<t>About to the generalization: if n=2 then the solution is x=sqrt(2). If n=4 then the solution is again x=sqrt(2), thus 2=4!!! Let’s analyze the function x^(1/x). It is zero for x->0, 1 for x=1, it has one max for x=e at e^(1/e) >1, and it is 1 for x->+infty (horizontal asymptote). It is easy to dr...

### Risk Reversals

Hi Anthony,From your formula, BF spread = ATM spread, however ICAP quotes for EUR-USD 3M areATM 10.10/10.35RR25D 0.1/0.4BF25D 0.175/0.275Do I miss something?Thanks a lot.
