The integral part of a nonlinear form with a square, a cube and a biquadrate

In this paper, we show that if λ1,λ2,λ3{\lambda }_{1},{\lambda }_{2},{\lambda }_{3} are non-zero real numbers, and at least one of the numbers λ1,λ2,λ3{\lambda }_{1},{\lambda }_{2},{\lambda }_{3} is irrational, then the integer parts of λ1n12+λ2n23+λ3n34{\lambda }_{1}{n}_{1}^{2}+{\lambda }_{2}{n}_{2...
