We evaluate the matrix elements 〈r〉 for the n-dimensional harmonic oscillator in terms of the dual Hahn polynomials and derive a corresponding three-term recurrence relation and a Pasternack-type reflection relation. A short review of similar results for nonrelativistic hydrogen atom is also given. 1. An Introduction The purpose of this note is to present a simple evaluation of the expectation ...
متن کاملSergei Nirenburg Marjorie McShane Stephen
In this paper, we briefly and informally illustrate, using a few annotated examples, the static and dynamic knowledge resources of ontological semantics. We then present the main motivations and desiderata of our approach and then discuss issues related to making ontological-semantic applications feasible through the judicious stepwise enhancement of static and dynamic knowledge sources while a...
متن کاملAdvertising Arbitrage by Sergei Kovbasyuk ( EIEF )
Speculators often advertise arbitrage opportunities in order to persuade other investors and thus accelerate the correction of mispricing. We show that in order to minimize the risk and the cost of arbitrage an investor who identifies several mispriced assets optimally advertises only one of them, and overweights it in his portfolio; a risk-neutral arbitrageur invests only in this asset. The ch...

متن کامل2 Sergei Igonin and Ruud Martini
We completely describeWahlquist-Estabrook prolongation structures (coverings) dependent on u, ux, uxx, uxxx for the Krichever-Novikov equation ut = uxxx−3uxx/(2ux)+p(u)/ux+ aux in the case when the polynomial p(u) = 4u−g2u−g3 has distinct roots. We prove that there is a universal prolongation algebra isomorphic to the direct sum of a commutative 2-dimensional algebra and a certain subalgebra of...
