The Canonical Model of a Singular Curve
(Springer, 2009-04)We give re fined statements and modern proofs of Rosenlicht's re- sults about the canonical model C′ of an arbitrary complete integral curve C. Notably, we prove that C and C′ are birationally equivalent if and only if ... -
A fundamental relation between phase and group velocity, and application to the failure of perfectly matched layers in backward-wave structures
(American Physical Society, 2009-06-11)We demonstrate that the ratio of group to phase velocity has a simple relationship to the orientation of the electromagnetic field. In nondispersive materials, opposite group and phase velocity corresponds to fields that ... -
Strictly small representations and a reduction theorem for the unitary dual
(American Mathematical Society, 2001)To any irreducible unitary representation X of a real reductive Lie group we associate in a canonical way, a Levi subgroup Gsu and a representation of this subgroup. Assuming a conjecture of the authors on the infinitesimal ...
