Newton-Maclaurin type inequalities for linear combinations of elementary symmetric functions
Shuqi Hu, Changyu Ren, Ziyi Wang
In this paper, we establish Newton-Maclaurin type inequalities for functions arising from linear combinations of primitively symmetric polynomials. This generalization extends the…
