SUMMARY
In two-dimensional space, many Quantum Field Theory (QFT) models exhibit renormalizability due to the simplification of loop integrals, which are represented as \(\int d^2 p\). This dimensionality reduces the complexity of divergences, allowing for consistent renormalization procedures. Additionally, there is a notable relationship between these QFT theories and the world-sheet formulation in string theory, as both frameworks utilize similar mathematical structures to describe physical phenomena.
