Let V be a two-dimensional real symmetric space with unit ball having 8n extreme points. Let λ(V) denote the absolute projection constant of V. We show that where is the space whose ball is a regular 8n-polygon. Also we reprove a result of [1] and [5] which states that for any two-dimensional real symmetric space V.

We establish a Carleman type inequality for the subelliptic operator in , , where , . As a consequence, we show that has the strong unique continuation property at points of the degeneracy manifold if the potential is locally in certain spaces.

In this article, we prove a series of differentiation identities [3] involving the secant and cosecant functions and specific combinations of special functions including trigonometric, exponential and logarithmic functions.
