In this lecture I will review some results about the discrete light-cone quantization (DLCQ) of strings and some connections of the results with matrix string theory. I will review arguments which show that, in the path integral representation of the thermal free energy of a string, the compactifications which are necessary to obtain discrete light-cone quantization constrains the integral over...

For some families of two-bridge knots, including double twist knots with genus at least four, we determine precisely the set integers n &gt; 1 <mml:annotation encoding="applicati...
