Abstract
A differential operator ℒ, arising from the differential expression
, and system of boundary value conditions
is considered in a Banach space E. Herev [k](t)=(a(t) d/dt) k v(t)a(t) being continuous fort⩾0, α(t) >0 for t > 0 and\(\int_0^1 {\frac{{dz}}{{a(z)}} = + \infty ;}\) the operator A is strongly positive in E. The estimates
, are obtained for ℒ: n even, λ varying over a half plane.
