- A Paley-Wiener Theorem for Convex Sets in Cn
Abstract. The basic Paley-Wiener theorem tells us that exactly those entire
functions of exponential type in C which are square-integrable over the
imaginary axis, are Laplace transforms of L2-functions on an interval.
This can be interpreted as an integral condition on two rays perpendicular
to the interval in question, and similar integral conditions are known
for general convex domains in C. We will show how we can obtain similar theorems for strongly convex domains in Cn.

- A new property of C-convex sets
Abstract. A subset U in Cn is said to be C-convex if its
intersection with any complex line is simply connected and
connected. Recently S. V. Znamenskij and L. N. Znamenskaya proved that
if a C-convex set U is non-degenerate, its intersections
with complex lines have an unexpected extra property: they are
spirally connected. I will present this result and discuss some of its
consequences.

- Necessary density conditions for sampling and interpolation
Abstract. We will discuss an article by Landau (1967) where he obtains necessary

interpolation of bandlimited functions in L2(Rn).
