The results provide validation of social norms governing sexual behavior, condom use, and substance use among friendship groups. These norms had strong to moderate h...

It is desirable, in certain situations, to establish multiple co-existi...

We show that every admissible representation of a real reductive group has a canonical system of Sobolev norms parametrized by positive characters of a minimal parabolic subgroup.
