Let X be a Banach space and A : D(A) ⊂ X −→ X be an unbounded linear operator on X. We study the concept of C0−semigroup of contraction on arbitrary Banach space X and give the two characterizations of A called infinitesimal ...

Optimizing the placement of new wells and well spacing is a vital issue in oil field development. Drilling infill wells is one way to maximize the recovery of oil from reservoirs. The problem of infill well placement is ...
