Title: An Application of Classical Analysis to Intertemporal Choice
Abstract:
There are many problems of longterm management and control arising in engineering, economics,
and other areas, where it is not desirable to set an exact time horizon or terminal date.
For example, in finding optimal replacement times for shortlived technical equipment, it is
often more natural and convenient to place the time horizon at infinity than to specify a
finite horizon. The infinitehorizon model leads to difficulties however, as concepts like
maximal aggregate payoff or utility need to be replaced with new ones. In this talk I will
discuss some philosophical and computational aspects of these difficulties and show how
ideas from classical analysis can be used to partially resolve them.

Speaker: Niklas Lundström, Department of Mathematics and Statistics, Umeå University

Place: E246
Title: pHarmonic Functions Near LowDimensional Hyperplanes
Abstract: We first give some basics about the pLaplace equation and pharmonic
functions including some applications. We then prove growth estimates of positive
pharmonic functions in ndimensional space vanishing near an mdimensional
hyperplane, 0 < m < n1. I.e. we consider "thin boundaries" of dimensions less than n1.
Our results imply the so called boundary Harnack's inequality, some
estimates of pharmonic measure
and some results of PhragmenLindelöf type for psubharmonic functions.
We will briefly sketch the proofs of which the core is constructions of
certain sub and supersolutions to the pLaplace equation.
