Let f(x) be a function defined on the positive integers such that:

f(x) = x/2 if x is even
f(x) = (3*x+1)/2 if x is odd

Is there such thing as an Odd Perfect Number

“What’s the geometrical meaning of the central extension of the algebra
of diffeomorphisms of the circle?
AKA
the 3X + 1 problem”.
Let f(x) be a function defined on the positive integers such that:

f(x) = x/2 if x is even
f(x) = (3*x+1)/2 if x is odd

Then the conjecture is: iterates of f(x) will eventually reach 1 for any
initial value of x.

please let me know if anyone of you manage to solve my problem of the diffeomorphisms of the circle as it has haunted me ten years.

Barbara and Mike – are you just doing a search on the internet for difficult math problems? A Scientist has posted identical issues that you both posted…The site is: http://www.newton.dep.anl.gov/askasci/math99/math99009.htm

Do every non-trivial zeros of the Riemann zeta function have a real part half???
