Oscillation of strongly noncanonical equations

New oscillation criteria for third order noncanonical differential equations of the form \[\left(r_2(t)\left(r_1(t)y (t)\right) \right) +p(t)y(\tau(t))=0\]are established. Our technique employs an equivalent canonical representation of the studied equation, which essentially simplifies the examination of noncanonical equations. The results obtained are supported by several illustrative examples.
