The String Equation in the Ftheory CosmologyComments: 8 pages, 1 figure
We give an explicit expression for the Ftheory string equations in the Ftheory model. We show that, in the absence of gravity, the equations form essentially the same as in the NielsonFrenkelAdS black hole model, but obtain the corresponding solutions in the class of $R^2$models. We also show that, in a subclass of $R^2$models, the KKmodel, the equations can be obtained from the solutions of the KKmodel with respect to the $R^2$models, and this class of models is also the "gold standard" for string equations in the Ftheory model.
