is there a function $gamma(x)$ where when $a$ & $b$ and $a+1$ & $b+1$ are co-prime, $gamma(frac{a}{b})>gamma(frac{a+1}{b+1})$

is there a function $gamma(x)$ where when $a$ & $b$ and $a+1$ & $b+1$ are co-prime, $gamma(frac{a}{b})>gamma(frac{a+1}{b+1})$ when you start with $gamma(frac{1}{2})$ you...

A quick way to tell local minimum given a sum of absolute value functions

Given a function $$f(k,x)=2|x-1|+k|x-2|+3|x-3|+|x-5|, ~~k=1,2,3$$ which is a five piece continuous function. The question is: can we can tell if there will exist a local minimum without plotting...

What is the order and structure of Aut(SL$_2(p)$)?

Here $p$ is a prime. We know that for $Z(SL_2(p)) = { pm I }$ and $lvert SL_2(p)rvert= p^3-p$ so there are $frac{p^3-p}{2}$ inner automorphisms. What...
