Relativistic Self-Dual Chern-Simons Systems: A Perspective
The self-dual systems are constrained and so are simpler to understand. In
recent years there have been several studies on the self-dual Chern-Simons
systems. Here I present a brief survey of works done by my collaborators and
myself. I also discuss several questions related to these self-dual models.Comment: LaTex, 9 pages, presented in the Low Dimensional Field Theory

Nahm Data and the Mass of 1/4-BPS States
The mass of 1/4-BPS dyonic configurations in N=4 D=4 supersymmetric
Yang-Mills theories is calculated within the Nahm formulation. The SU(3)
example, with two massive monopoles and one massless monopole, is considered in
detail. In this case, the massless monopole is attracted to the massive
monopoles by a linear potential.Comment: 23 pages, 2 Postscript figures, v2 references added and typos

Little strings on orbifolds
We explore two classes of 6d little string theories
obtained from type IIA/IIB NS5-branes probing singularities. Their tensor
branches are described by effective gauge theories whose instanton solitons are
macroscopic little strings. We specifically study two families of 2d
gauge theories which describe at low energy the worldsheet
dynamics of the type IIA/IIB little strings. These gauge theories are useful to
calculate the supersymmetric partition functions of the little string theories
on . We establish the T-duality of the little string
theories by utilizing their BPS spectra as a probe.Comment: 29 pages, 9 figures; v2: minor changes, published versio
