Define `genPbEquiv`

Introduction

In the realm of mathematical formalization, the concept of genPbEquiv plays a crucial role in defining the universal property of a given structure. In this article, we will delve into the details of genPbEquiv and explore its implementation in the context of the ForPoly and NaturalModelBase frameworks. We will also discuss the specialization of this universal property to the groupoid model, as outlined in Lemma 4.4.3.

The Universal Property of R

In Lemma 5.0.3, we define the universal property of R in the context of the ForPoly framework. This property is a fundamental aspect of the R structure, and its definition serves as a building block for more complex constructions. The universal property of R can be stated as follows:

• Definition 1: Let R be a given structure, and let UvPoly be a universal property of R. Then, genPbEquiv is a function that takes UvPoly as input and returns an equivalence relation between R and another structure, denoted as R'.

Specializing the Universal Property

In Lemma 4.4.3, we specialize the universal property of R to the groupoid model. This specialization is crucial in defining the baseGenPbEquiv function in the GroupoidModel.NaturalModelBase.lean file. However, this definition is currently implemented using the sorry tactic, which is not ideal. Instead, we can use the more general NaturalModelBase.genPbEquiv function in the Russell_PER_MS.NaturalModelSigma.lean file to define the baseGenPbEquiv function.

Defining genPbEquiv in ForPoly

To address the first point, we need to define the UvPoly-general version of genPbEquiv in the ForPoly framework. This involves creating a function that takes UvPoly as input and returns an equivalence relation between R and R'. The implementation of this function will depend on the specific details of the ForPoly framework and the universal property of R.

Defining genPbEquiv in NaturalModelBase

Once we have defined the UvPoly-general version of genPbEquiv in ForPoly, we can use this definition to create the NaturalModelBase-general version of genPbEquiv. This involves specializing the UvPoly-general version to the NaturalModelBase framework, which will require additional implementation details.

Defining genPbEquiv in GroupoidModel

Finally, we can use the NaturalModelBase-general version of genPbEquiv to define the GroupoidModel version of genPbEquiv. This involves specializing the NaturalModelBase-general version to the groupoid model, which will require additional implementation details.

Conclusion

In this article, we have explored the concept of genPbEquiv and its implementation in the context of the ForPoly and NaturalModelBase frameworks. We have also discussed the specialization of this universal property to the groupoid model, as outlined in Lemma 4.4.3. By defining genPbEquiv in ForPoly, NaturalModelBase, and GroupoidModel, we can create a comprehensive and consistent implementation of this universal property across different frameworks.
