<fontfamily><param>Helvetica</param>Greetings,


Yes, I have been quite tardy is getting this out. Sorry about that. =
Attached is a draft DTD for the OAMS, called appropriately enough =
oams.dtd. The DTD is quite simple. Please look it over and comment. A =
record complying with the DTD is also attached.


Several issues should be discussed here:


1) What entities for special characters (if any) to use? I lifted the =
set from the MathML DTD which I think is rather complete for what we are =
doing here. They can be downloaded from =
http://www.nag.co.uk/projects/openmath/mml-files/mml101ents.html


2) Should we create an OAMS XML namespace?


Cheers,

Mark

<title>Dilaton Contact Terms in the Bosonic and Heterotic

<abstract>Dilaton contact terms in the bosonic and heterotic strings are =
examined following the recent work of Distler and Nelson on the bosonic =
and semirigid strings. In the bosonic case dilaton two-point functions =
on the sphere are calculated as a stepping stone to constructing a good =
coordinate family for dilaton calculations on higher genus surfaces. It =
is found that dilaton-dilaton contact terms are improperly normalized, =
suggesting that the interpretation of the
dilaton as the first variation of string coupling breaks down when other =
dilatons are present. It seems likely that this can be attributed to the =
tachyon divergence found in Ref 1. For the heterotic case, it is found =
that there is no tachyon divergence and that the dilaton contact terms =
are properly normalized. Thus, a dilaton equation analogous to the one =
in topological gravity is derived and the interpretation of the dilaton =
as the string coupling constant goes through.</abstract>
