quadratic reciprocity law

[bhelmes]

A peaceful day for all members,

Does there exist only one quadratic reciprocity law,
or do there exist several quadrac reciprocity laws
depending on the quadratic polyonoms,

resp. is the quadratic reciprocity law the same for
gaussian and eisenstein primes.

https://en.wikipedia.org/wiki/Eisenstein_prime

Thanks in advance for a clear answer,
Bernhard

With Eisenstein primes, you'd more likely be dealing with cubic reciprocity.

It should be possible to formulate quadratic reciprocity for the Eisenstein integers. I'm not sure how, offhand.

Maybe the "Eisenstein integers" section of the Wikipedia article about "Cubic reciprocity" might be a start.

A peaceful night for you,


is there a special quadratic reciprocity law for the polynomial f(n)=2n^2-1 ?


It might be also interesting for other persons.
