The August 1999 issue of Genome Research presented a very interesting editorial, “Hypothesis-Limited Research,” on the status and discovery function of scientific hypotheses in disciplines generating large amounts of data (Goodman 1999). Dr. Goodman points to two types of limitations generated by hypotheses—one theoretical and one pragmatic. She argues that generating at least some type of data...

We consider the Nelson model on some static space-times and investigate the problem of absence of a ground state. Nelson models with variable coefficients arise when one replaces in the usual Nelson model the flat Minkowski metric by a static metric, allowing also the boson mass to depend on position. We investigate the absence of a ground state of the Hamiltonian in the presence of the infrare...
