Abstract
Let P be an elliptic differential operator of order p with real analytic coefficients on in open set Q โ โ^n^. Given a compact set K โ ฮฉ, we describe the closure in BMO(K) of the space of mentions of Pf = 0 on neighborhoods of K.

Let f be a Borel measurable function of the complex plane to itself. We consider the nonlinear operator T f defined by T f [g]=f p g, when g belongs to a certain subspace X of the space BMO(R n ) of functions with bounded mean oscillation on the Euclidean space. In particular, we investigate the cas
Let X be a perfect, compact subset of the complex plane, let (M n ) be a sequence of positive numbers satisfying M 0 =1 and ( m+n n ) M m+n รM m M n , and let D(X, M) With pointwise addition and multiplication, D(X, M) is a commutative normed algebra. In this note we study the endomorphisms of such
