### 29 november, Kurt Johansson (KTH):
Determinantal processes and number variance saturation

**Abstract.**
I will discuss the construction of determinantal
point processes on the real line which have the interesting
feature that they show number variance saturation. This means
that the variance of the number of particles in an interval
converges to a limiting value as the length of the interval goes to
infinity. Number variance saturation is also seen for example in the
zeros of the Riemann zeta-funtion and in quantum chaos, but these
only serve as a motivation and I will not present any new results
for these. The construction is based on non-intersecting Brownian
paths.
