Outline of Final Research Achievements |
(1) 1-dimensional Schroedinger operator H with decaying white noise potential is considered, and its spectral properties are determined when the decaying factor is square integrable. Also, the property of a part of the spectrum of H is determined when the decaying factor is not square integrable. (2) Based on a mathematical model which incorporates a hypothesis that adult males and females are mildly segregated in their social life, it is shown that a condition is ready for the 2013 rubella outbreak in Japan. By another mathematical model, possible consequences of the rubella vaccination limited to schoolgirls were shown. (3) A stochastic model is constructed in order to clarify the notion of "generation interval" in infectious disease epidemiology.
