Abstract
We consider second-order difference expressions,
with complex coefficients, of the form
wn−1[−Δ(pn−1Δxn−1)+qnxn] acting on infinite sequences. The discrete analog of some known relationships
in the theory of differential operators such as Dirichlet, conditional
Dirichlet, weak Dirichlet, and
strong limit-point is considered. Also, connections and some relationships
between these properties have been established.
