(Update): Courtesy of Myerson's and Elkies' answers, we find a second cyclic quintic for $\cos\frac{2\pi}{p}$ with $p=\text{1 mod 10}$ as, $$\frac{z^5}{\beta} = 10 z^3 - 20 n^2 z^2 + 5 (3 n^4 - 25 n^2 - 625) z - 4 n^2 (n^4 - 25 n^2 - 125)$$ where $\beta=n^4 + 25 n^2 + 125.$ Its discriminant is, $$D=2^{12}\,5^{20}\,(n^4+7n^2)^2\,(n^4 + 25 n^2 + 125)^4$$ Finding a parametric cyclic quintic was one of the aims of this post.


(Original post): We have $$x^5 + x^4 - 4 x^3 - 3 x^2 + 3 x + 1=0,\quad\quad x =\sum_{k=1}^{2}\,\exp\Bigl(\tfrac{2\pi\, i\, 10^k}{11}\Bigr)$$ and so on for prime $p=10m+1$. Let $A$ be this class of quintics with $x =\sum_{k=1}^{2m}\,\exp\Bigl(\tfrac{2\pi\, i\, n^k}{p}\Bigr).$ I was trying to find a pattern to the coefficients of this infinite family, perhaps something similar to the Diophantine equation $u^2+27v^2=4N$ for the cubic case.

First, we can depress these (get rid of the $x^{n-1}$ term ) by letting $x=\frac{y-1}{5}$ to get the form, $$y^5+ay^3+by^2+cy+d=0$$ Call the depressed form of $A$ as $B$.

Questions:

  1. Is it true that for $B$, there is always an ordering of its roots such that$$\small y_1 y_2 + y_2 y_3 + y_3 y_4 + y_4 y_5 + y_5 y_1 - (y_1 y_3 + y_3 y_5 + y_5 y_2 + y_2 y_4 + y_4 y_1) = 0$$
  2. Do its coefficients $a,b,c,d$ always obey the Diophantine relations, $$a^3 + 10 b^2 - 20 a c= 2z_1^2$$ $$5 (a^2 - 4 c)^2 + 32 a b^2 = z_2^2$$ $$(a^3 + 10 b^2 - 20 a c)\,\big(5 (a^2 - 4 c)^2 + 32 a b^2\big) = 2z_1^2z_2^2 = 2(a^2 b + 20 b c - 100 a d)^2$$ for integer $z_i$?

I tested the first forty such quintics and they answer the two questions in the affirmative. But is it true for all prime $p=10m+1$?

I think the depressed quintic in the question is what Emma Lehmer called the reduced quintic in her paper, The quintic character of 2 and 3, Duke Math. J. Volume 18, Number 1 (1951), 11-18, MR0040338. In the proof of Theorem 4, she writes that the reduced quintic is $$F(z)=z^5-10pz^3-5pxz^2-5p\left({x^2-125w^2\over4}-p\right)z+p^2x-{x^3+625(u^2-v^2)w\over8}$$ where $16p=x^2+50u^2+50v^2+125w^2$, $xw=v^2-u^2-4uv$ determines $x$ uniquely. You might plug these into your conjectured diophantine relations, to see whether they hold.

EDIT:

A slightly different formula is given by Berndt and Evans, The determination of Gauss sums, Bull Amer Math Soc 5, no. 2 (1981) 107-129, on page 119 (formula 5.2). It goes $$ F(z)=z^5-10pz^3-5pxz^2-5p\left({x^2-125w^2\over4}-p\right)z+p^2x-p{x^3+625(u^2-v^2)w\over8} $$ the difference being the factor of $p$ in the last term. Berndt and Evans note that Lehmer inadvertently omitted this factor.

Update: (by OP)

Using the edited coefficients of $F(z)$ by Berndt and Evans, if we express it as, $$z^5+az^3+bz^2+cz+d=0$$ and taking into account $16p=x^2+50u^2+50v^2+125w^2,\,x=(v^2-u^2-4uv)/w$, then $$a^3 + 10 b^2 - 20a c =2\times125^2p^2w^2=2z_1^2$$ $$5(a^2 - 4c)^2 + 32a b^2 = 500^2 p^2(u^2 - u v - v^2)^2=z_2^2$$ $$(a^3 + 10 b^2 - 20 a c)\,\big(5 (a^2 - 4 c)^2 + 32 a b^2\big) = 2(a^2 b + 20 b c - 100 a d)^2$$ which confirms all three Diophantine relations by the OP.

  • $\begingroup$ I tried Lehmer's quintic on $F(z)$ and can't get it to work. Can you check if $F(z)$ has a typo, especially on the constant term? $\endgroup$ Commented Nov 24, 2016 at 1:50
  • $\begingroup$ You may be right. I've edited to include another opinion. $\endgroup$ Commented Nov 24, 2016 at 2:22
  • $\begingroup$ I thought so. By the way, I added an update to your answer as it was too long for a comment. I hope you don't mind. It confirms the first two Diophantine relations. And the third is confirmed by Elkies' answer. $\endgroup$ Commented Nov 24, 2016 at 7:15
  • $\begingroup$ It's beautiful that the quadratic forms for the cubic and quintic cases are $$\alpha^2+27\beta^2=4p$$ $$\alpha^2+10\beta^2+50\gamma^2+125\delta^2=16p$$ Googling it, the one for septics is a tad more complicated. And thanks for this answer. Because of this, I found a second cyclic family of quintics rather simple in form (which has been added to the post). $\endgroup$ Commented Nov 24, 2016 at 7:58

Question 1: Yes; in fact $$ \sum_{n\bmod 5} y_n y_{n+1} = \! \sum_{n\bmod 5} y_n y_{n+2} = -p/5 $$ for the "depressed" $y_n$, using an order consistent with the action of the cyclic Galois group. Likewise "for other values of 5".

This follows from the formula $|\tau|^2 = p$ for the absolute value of a nontrivial Gauss sum $\tau$, together with the observation that the quintic Gauss sums are the values at $m \neq 0$ of the discrete Fourier transform $\hat y$ of $\vec y$: $$ \tau_m = \sum_{n \bmod 5} e^{2\pi i mn/5} y_n $$ (and $\tau_0 = 0$ thanks to the "depression"). Now the $y_n$ are real, so $\bar\tau$ is the Fourier transform of the map $n \mapsto y_{-n}$; thus the autocorrelation function $$ c_j = \sum_{n \bmod 5} y_n y_{n+j} $$ is the convolution of $\vec y$ with $n \mapsto y_{-n}$, whence the Fourier transform $\hat c$ is $\tau \bar \tau = |\tau|^2$. But that's $0$ at $m=0$, and $p$ otherwise; therefore $c_0 = 4p/5$ and $c_j = -p/5$ for other $j$. In particular $c_1 = c_2$, QED.

P.S. I was using $x = y - \frac15$, not your $x = \frac{y-1}{5}$, so most formulas above will have to be scaled by suitable powers of $5$ to apply to your $y$'s.

  • $\begingroup$ This also confirms the third Diophantine relation. Thanks and I wish I could accept two answers. $\endgroup$ Commented Nov 24, 2016 at 7:23
  • $\begingroup$ It's been a while. Perhaps this new question in transforming a two-parameter $5T2$ quintic into a one-parameter $5T1$ quintic might be of interest. $\endgroup$ Commented Dec 30, 2022 at 13:22

CW. Here are the first 250 examples, by the method of Gauss in section VII of the Disquisitiones. I followed Galois Theory by David A. Cox, chapter 9. The quintic for a prime $p \equiv 1 \pmod 5$ is $$ x^5 + x^4 - 2 \left( \frac{p-1}{5} \right) x^3 + a x^2 + b x + c $$ with integers $a,b,c.$ Gerry has indicated that there is likely to be additional detail in Storer.

    $\begingroup$ Thanks. Courtesy of the answers by Myerson and Elkies, the depressed forms of these satisfy the three Diophantine relations in the post. And I edited the post to include a second simple cyclic family which, incidentally, contains $p=151$. $\endgroup$ Commented Nov 24, 2016 at 7:51

    $\begingroup$ I checked Storer's book, he doesn't do the quintic. $\endgroup$ Commented Nov 24, 2016 at 11:46
  • $\begingroup$ @GerryMyerson:The corrected Lehmer quintic does satisfy all three Diophantine relations. (I made a small typo when I was checking it earlier.) $\endgroup$ Commented Nov 24, 2016 at 13:10
