Abstract

The purpose of the paper is to show that noncanonical operator

Ly=r2(t)r1(t)y′(t)′′

can be easily written in essentially unique canonical form

Ly=q3(t)q2(t)q1(t)q0(t)y(t)′′′

such that

∫∞1qi(s)ds=∞,i=1,2.

The canonical representation is applied for examination of the third order noncanonical equations

r2(t)r1(t)y′(t)′′+p(t)y(τ(t))=0.
Keywords: canonical operator; third order differential equations; disconjugate equation
