An elementary proof of Hilbert's theorem on ternary quartics: Some complements
Albrecht Pfister, Claus Scheiderer
In 1888, Hilbert proved that every nonnegative quartic form with real coefficients is a sum of three squares of quadratic forms. His proof was ahead of its time and us…

An elementary proof of Hilbert's theorem on ternary quartics
Albrecht Pfister, Claus Scheiderer
In 1888, Hilbert proved that every non-negative quartic form f=f(x,y,z) with real coefficients is a sum of three squares of quadratic forms. His proof was ahead of its time and use…
