Approximation On Totally Real Manifolds,Twenty years ago JohnWermer and the author [4] proved a theorem on approximation by analytic functions on a totally real submanifold of .. One part of the argument was quite precise and assumed only that the manifold was of class .. However, another part using . estimates required higher differentiability assumptions, depending on the dimension ..

Remarks On Convexity With Respect To Operators Of Real Principal Type,-convexity with respect to singular supports has been completely characterized in geometrical terms when . is an operator of principal type. (See [2, section 1.4].) However, no satisfactory geometrical interpretation of .-convexity (with respect to supports) is known even when . is of real principal type as we shall assume throughout this paper.

An Isoperimetric Inequality In Homogeneous Finsler Spaces,mogeneous and non-isotropic”, that is measured with some non-euclidean (and not even convex) metric. — The idea of the proof is due to E. Schmidt. However, as this author works quite insymmetrically our formalism has to be quite different.
