Factorization of Toeplitz and Hankel operators

Vlastimil Pták (1997)

Mathematica Bohemica

Similarity:

Using a factorization lemma we obtain improvements and simplifications of results on representation of generalized Toeplitz and Hankel operators as compression of symbols.

Asymptotic properties of solutions of second order quasilinear functional differential equations of neutral type

Takaŝi Kusano, Pavol Marušiak (2000)

Mathematica Bohemica

Similarity:

This paper establishes existence of nonoscillatory solutions with specific asymptotic behaviors of second order quasilinear functional differential equations of neutral type. Then sufficient, sufficient and necessary conditions are proved under which every solution of the equation is either oscillatory or tends to zero as t → ∞ .
