This short introduction to microlocal analysis is presented, in the spirit of Hörmander, in the
classical framework of partial differential equations. This theory has important applications in …

Purpose: This study is part of a larger project whose aim is to evaluate the relationship
between refractive errors and amblyopia. In an earlier study, we showed that there is a …

In this paper we shall present what we think is the natural extension of H~ rmander's theory
of Fourier integral operators to the case of complex valued phase functions. it is a well …

Unexpected spinal anesthesia, occurring after peripheral nerve blocks close to the spine,
may be caused by a centripetal spread of the local anesthetic along the injected nerve to the …

In this note we introduce, without explicit reference to any derivatives, a normed space of
symbols on R2n which is contained in the classical symbol space S0 0, 0 of smooth …

Forty-four children aged 2-9 years with strabismic and anisometropic amblyopia were
prospectively followed up during amblyopia treatment. The efficacy of optimised treatment in …

Purpose: 1045 children between 12 and 13 years old were examined in a field study in the
Göteborg area (Sweden). The aim of this study was to report the prevalence of refractive …
