Updated on Friday 15th March 2019 at 5 pm in the light of comments received over the last 24 hours.



The original question was; given the well known variation of Binet's Formula:
$$F_n = fracphi^n - (-phi)^-nsqrt5$$



Derive an elegant expression, should one exist, for;
$$F_log (n) + F_log(n)-1$$



Of course,
$$phi=frac1+sqrt52$$



Wolfgang Kais has pointed out that this is going to run into technical issues with raising negative numbers to the power of $log(n)$.



Consequently, initially at least, I've been looking instead at
$$F_f(n) + F_f(n)-1$$
where the function $f$ is sufficiently well behaved to not run into such issues.



In this case,



$$ (sqrt5)(F_f(n) + F_f(n)-1)=phi^f(n)-(-phi)^-f(n)+ phi^f(n)-1-(-phi)^-(f(n)-1)$$
Using the two equivalent facts that
$$1-phi=- frac1phi :or: phi=1+frac1phi$$



I proceeded as follows;



$$ (sqrt5)(F_f(n) + F_f(n)-1)=phi^f(n)-big(-frac1phibig)^f(n)+ phi^f(n) times phi^-1-big(-frac1phibig)^(f(n)-1)$$



$$ =phi^f(n)-(1-phi)^f(n)+ fracphi^f(n)phi-big(-frac1phibig)^f(n) times big(-frac1phibig)^-1$$



$$ =phi^f(n)big(1+frac1phibig)-(1-phi)^f(n)-(1-phi)^f(n) times (-phi)$$
$$ =phi times phi^f(n) - (1-phi) times (1-phi)^f(n)$$



Wolfgang Kais suggested immediately starting with the Fibonacci recurrence relation
$$F_m=F_m-1+F_m-2$$
from which I deduce that
$$F_f(n)+F_f(n)-1=F_f(n)+1$$
Now, applying the variation on Binet's Formula,
$$F_f(n)+1 = fracphi^f(n)+1 - (-phi)^-(f(n)+1)sqrt5$$



$$(sqrt5)(F_f(n)+1) = phi times phi^f(n) - big(-frac1phibig)^f(n)+1$$
$$ = phi times phi^f(n) - (1-phi)^f(n)+1$$
$$ =phi times phi^f(n) - (1-phi) times (1-phi)^f(n)$$



which is the same result as obtained previously which, if nothing else, shows that the variation on Binet's formula satisfies the Fibonacci Recurrence relation.



I'm curious to know if
$$ F_f(n)+1 = fracphi times phi^f(n)sqrt5 - frac(1-phi) times (1-phi)^f(n)sqrt5$$
is of any use, and is it the best that can be done ?



Possibly I've exhausted what can usefully be done with this question, as I can't see the point of introducing the $log(n)$ function, given the technical hurdles it immediately throws up.



However, any further thoughts are most welcome.

    @Wolfgang Kais : Of course ! And if I use that in the Binet formula I can get to $$F_log (n) + F_log(n)-1 = frac phi times phi^log (n)-(1-phi) times (1- phi)^log(n)sqrt5$$ which is so similar to the expression I mention in my question that I think I have a single minus sign error and so have $phi^2$ instead of $(1 - phi)$.

    You can also try and use the identity $$x^log a=a^log x.$$ Unfortunately that requires careful interpretation of complex powers unless $a$ and $x$ are both positive real numbers. It does give you a simple estimate for the sum.

@MartinHansen
Sorry i cant comment as i have reputation less than 50



$$F_log (n) + F_log(n)-1 = frac phi^logn-(-phi)^-log(n)sqrt5+frac phi^log(n)-1-(-phi)^-(log(n)-1)sqrt5$$
$$log (n) + F_log(n)-1 = frac phi^log(n)+(phi)^(log(n)-1)sqrt5+frac phi^-log(n)+(phi)^-(log(n)-1)sqrt5$$



as in asymptotic time complexity we tends to ignore constants
$$log (n) + F_log(n)-1 = phi^log(n)+(phi)^(log(n)-1)+phi^-log(n)+(phi)^-(log(n)-1)$$
How can i proceed further from here

    Sorry i cant comment as i have reputation less than 50



    $$F_log (n) + F_log(n)-1 = frac phi^logn-(-phi)^-log(n)sqrt5+frac phi^log(n)-1-(-phi)^-(log(n)-1)sqrt5$$
    $$log (n) + F_log(n)-1 = frac phi^log(n)+(phi)^(log(n)-1)sqrt5+frac phi^-log(n)+(phi)^-(log(n)-1)sqrt5$$



    as in asymptotic time complexity we tends to ignore constants
    $$log (n) + F_log(n)-1 = phi^log(n)+(phi)^(log(n)-1)+phi^-log(n)+(phi)^-(log(n)-1)$$
    How can i proceed further from here
