Certain inequalities and constants related with a nonlinear differential equation. II. (English) Zbl 0656.34030
The author derives through lengthy and complicated calculations some inequalities, which will be used to extend the validity of his conjecture C to $$3<n<5$$ in a forthcoming paper. [For part I see ibid. 21, 5-35 (1985; Zbl 0591.53043).]
