Abstract

In this Paper we explore a few issues which have their foundations in both topological string theory and enumerative geometry. In the previous case, fundamental speculations are topological field hypotheses, though the last case is worried about convergence hypotheses on moduli spaces. A saturating topic in this proposal is to look at the nearby interchange between these two integral fields of study. The primary issues tended to are as per the following: In considering the Hurwitz specification issue of branched covers of reduced associated Riemann surfaces, we totally take care of the issue on account of basic Hurwitz numbers. Furthermore, using the association between Hurwitz numbers and Hodge integrals, we determine a producing capacity for the last on the moduli space Mg,2 of 2-pointed, genusg Deligne-Mumford stable curves. We likewise explore Givental's ongoing guess with respect to semi straightforward Frobenius structures and Gromov-Witten invariants, the two of which are firmly identified with topological field hypotheses; we consider the instance of a complex projective line P1 as a particular model and check his guess at low genera. In the last section, we show that specific topological open string amplitudes can be processed by means of relative stable morphisms in the algebraic class.
