Strongly Oscillatory and Nonoscillatory Subspaces of Linear Equations
Strongly Oscillatory and Nonoscillatory Subspaces of Linear Equations
Consider the nth order linear equation and particularly the third order equation A nontrivial solution of (1) n is said to be oscillatory or nonoscillatory depending on whether it has infinitely many or finitely many zeros on [a, ∞). Let denote respectively the set of all solutions, oscillatory solutions, nonoscillatory …
