Just an amateur with very limited general knowledge; not only limited math knowledge.

Feb 19	comment	Least power. Squares again Ok; i see know. But it would have been clearer to say Product () -Product () = 2f(0) = constant. I thought, first, c was an arbitray external constant. This is why i did not iunderstand.
Feb 19	comment	Least power. Squares again Though there is the short posibility of g(0)=2(2k+1)=4k+2 with no solution.
Feb 19	comment	Least power. Squares again I do not understand quite well the step where it is said that Product(x+ai)-Product(x+bi) is a constant
Feb 19	comment	Least power. Squares again Andreas, your proof seems correct to me. Just you should not say g(0) is odd "avant la lettre". In my opinion g(0) must be odd because u and v have distint parity and we must have uv = 2^(k/2-1)g(0)^2 so g(0) must be odd. Also i agree k must be a multiple of 4, because half the multiplied terms are negative and a square is always positive. The only small doubt i have is the validity/generality of the choosen x= (k-1)/2, a non integer value for x; to give the full proof.

Feb 18	comment	Least power. Squares again Thank you for the answers. I thought i had a proof by induction for the case k=4 but it was not a correct proof. Sorry for it.

Feb 3	comment	Many kinds of Infinitely many Your math argument begins well, the inductive part, but then there are errors. But it could also be i am unable to understand your math style.

Feb 2	comment	Many kinds of Infinitely many Gerry; though not more than an amateur; what i like about maths is its decency; no way, in general, to tamper. I offer 20 € (European Euros) if you´re able for a decent math statement. Not alchemy, please.
