Note:These pages make extensive use of the latest XHTML and CSS Standards. They ought to look great in any standards-compliant modern browser. Unfortunately, they will probably look horrible in older browsers, like Netscape 4.x and IE 4.x. Moreover, many posts use MathML, which is, currently only supported in Mozilla. My best suggestion (and you will thank me when surfing an ever-increasing number of sites on the web which have been crafted to use the new standards) is to upgrade to the latest version of your browser. If that's not possible, consider moving to the Standards-compliant and open-source Mozilla browser.

Papers on Superpotentials

Frank Ferrari has given a nice field-theoretic proof of (the simplest case of) the Dijkgraaf-Vafa proposal, using the methods of Intriligator-Leigh-Seiberg. The nifty thing is that the linearity of the effective superpotential, Weff, in the coupling constants, gp of tree-level superpotential Wtree= gp Tr Φp/p (one of the main conclusions of ILS) is precisely equivalent to the statement of DV that only planar diagrams of the matrix integral contribute to Weff.

Meanwhile, Becker and Constantin carry out some checks of Gukov’s conjecture about the form of the effective superpotential in String/M-theory compactifications with background fluxes.
