Questions about Number Fields
As for number fields: I do suggest onto studying them by using generating polynomial rather than ring of integers in Z[d^(1/k)]
(1) Consider ring of integers in Q[sqrt(6)]. What's the polynomial generating this number field. Is
it x^2+6?
(2) Is the polynomial generating all set of Gaussian integers is being x^2+1?
(3) Does the set of numbers of form x*sqrt(2)+y*sqrt(3) really form a number field? x, y are being integers.
Apparently it is not being closed: as follows as: [a*sqrt(2)+b*sqrt(3)]*[c*sqrt(2)+d*sqrt(3)]
= 2ac3bd+sqrt(6)*(ad+bc).
(4) What are the number field elements being generated by using polynomial 2*x^2+3? Is it being isomorphic
with x^2+6? Or does it not generate with number field at all. What about 3*x^2+2 and 6*x^2+1? Which of them
are being isomorphic with each other? Or that one or more of these polynomials does not generate with a number field at all?
(5) Of number fields being generated by using following polynomials: x^2+5, 5*x^2+1, 2*x^2+2*x+3, 3*x^2+2*x+2
all of same discriminant value of 20, of course,
which of them are being isomorphic to each other; which of them do not generate a number field at all?
(6) What are ring of integers being generated by using following polynomial
as follows as: 2*x^2+2*x+3? Is it being a valid statement, first of all?
(7) What do the ring of integers in Z[cbrt(2)] look like? Are they being p+q*cbrt(2)+r*cbrt(4)? p, q, r are being integers.
Does their norm will have inherited multiplicative property  i.e. product of norm of two integers in Z[cbrt(2)] will also
be a norm of some integer in Z[cbrt(2)], as in quadratic fields ... ?
(a^2+k*b^2)(c^2+k*d^2)
= a*d+k*b*c^2 + k*a*db*c^2
= a*dk*b*c^2 + k*a*d+b*c^2
What is its generating polynomial for this following number field being? Is it x^32?
(8) Ring of integers being generated by using following polynomial x^31 is always being necessarily of following form
p+q*omega+r*omega^2? p, q, r are being integers.
(9) How do I determine ring of integers in number field being generated by using polynomial x^4x^3+x^2x+1? How do I determine
which of number fields generated by using of what other polynomials of same degree  (in this case  4) are being isomorphic onto it?
(10) Consider number fields being generated by using some special polynomials cases as follows as:
x^5+x^4+4*x^33*x^23*x+1; being used with some Cunningham number; exponent of some multiple of 11.
x^6x^55*x^4+4*x^3+6*x^23*x1; being used with some Cunningham number; exponent of some multiple of 13.
How do I determine ring of integers in number field being generated by using it?
(11) Are there being some type of number fields being generated by using some of the other functions, e.g. for instance
trigonometric / logarithmic / exponential / hyperbolic functions, besides that of algebraic / polynomial functions alone?
(12) Prove that prime numbers p of form x^2+27*y^2 (discriminant = 108) are being for which 2 is being a cubic residue (mod p).
Prove that prime numbers p of form x^2+32*y^2 (discriminant = 128) are being for which 4 is being an octic residue (mod p).
Prove that prime numbers p of form x^2+64*y^2 (discriminant = 256) are being for which 2 is being a biquadratic residue (mod p).
Prove that if prime number p ≡ 1 (mod 3), 3 is being a cubic residue (mod p), and then that 4*p is being of form x^2+243*y^2.
Prove that prime numbers p of form 4*x^2+2*x*y+7*y^2 (discriminant = 108) are being for which 2 is being a cubic nonresidue (mod p).
Prove that prime numbers p of form 4*x^2+4*x*y+9*y^2 (discriminant = 128) are being for which 4 is being an octic nonresidue (mod p).
Prove that prime numbers p of form 4*x^2+4*x*y+17*y^2 (discriminant = 256) are being for which 2 is being a biquadratic nonresidue (mod p).
I need on to know a few things on to
