Functions in the class $ U_{2p}^{*} $ are represented as $ g(z) = c(z)f(z) $ where $ f\\in U_{2p} $ and c is a real polynomial with no real zeros. Every real entire function g , of finite order with at most finitely many non-real zeros satisfies $ g\\in U_{2p}...

Suppose that f(x) and g(x) have only real zeros and that g interlaces f or g alternates left of f. We show that if ad⩾bc then the polynomial (bx+a)f(x)+(dx+c)g(x)has only real zeros. Applications are related to certain results of Brenti (Mem. Amer. Math. Soc. 413 (...
