The set of charges which minimally allows a potential term
i. Overview
In this module given finite sets for the `5`-bar and `10`d charges `S5` and `S10` we find the sets of charge spectra which minimally allowed a potential term `T`. The set we will actually define will be a multiset, for computational efficiency (using multisets saves Lean having to manually check for duplicates, which can be very costly)
To do this we define some auxiliary results which create multisets of a given cardinality from a finset.
ii. Key results
- `minimallyAllowsTermsOfFinset S5 S10 T` : the multiset of all charge spectra with charges in `S5` and `S10` which minimally allow the potential term `T`. - `minimallyAllowsTerm_iff_mem_minimallyAllowsTermOfFinset` : the statement that `minimallyAllowsTermsOfFinset S5 S10 T` contains exactly the charge spectra with charges in `S5` and `S10` which minimally allow the potential term `T`.

A. Construction of set of charges which minimally allow a potential term
We start with the construction of the set of charges which minimally allow a potential term, and then later prover properties about this set. The set we will define is `minimallyAllowsTermsOfFinset`, the construction of which relies on some preliminary results.
A.1. Preliminary: Multisets from finite sets
We construct the multisets of cardinality `1`, `2` and `3` which contain elements of finite set `s`.
#### A.1.1. Multisets of cardinality `1`
#### A.1.2. Multisets of cardinality `2`
#### A.1.3. Multisets of cardinality `3`
A.2. `minimallyAllowsTermsOfFinset`: the set of charges which minimally allow a potential term
Given the construction of the multisets above we can now define the set of charges which minimally allow a potential term.
We will prove it has the desired properties later in this module.
A.3. Showing `minimallyAllowsTermsOfFinset` has charges in given sets
We show that every element of `minimallyAllowsTermsOfFinset S5 S10 T` is in `ofFinset S5 S10`. That is every element of `minimallyAllowsTermsOfFinset S5 S10 T` has charges in the sets `S5` and `S10`.
B. Proving the `minimallyAllowsTermsOfFinset` is set of charges which minimally allow a term
We now prove that `minimallyAllowsTermsOfFinset` has the property that all charges spectra with charges in the sets `S5` and `S10` which minimally allow the potential term `T` are in `minimallyAllowsTermsOfFinset S5 S10 T`, and vice versa.
B.1. An element of `minimallyAllowsTermsOfFinset` is of the form `allowsTermForm`
We show that every element of `minimallyAllowsTermsOfFinset S5 S10 T` is of the form `allowsTermForm a b c T` for some `a`, `b` and `c`.
B.2. Every element of `minimallyAllowsTermsOfFinset` allows the term
We show that every element of `minimallyAllowsTermsOfFinset S5 S10 T` allows the term `T`.
B.3. Every element of `minimallyAllowsTermsOfFinset` minimally allows the term
We make the above condition stronger, showing that every element of `minimallyAllowsTermsOfFinset S5 S10 T` minimally allows the term `T`.
B.4. Every charge spectra which minimally allows term is in `minimallyAllowsTermsOfFinset`
We show that every charge spectra which minimally allows term `T` and has charges in the sets `S5` and `S10` is in `minimallyAllowsTermsOfFinset S5 S10 T`.
B.5. In `minimallyAllowsTermsOfFinset` iff minimally allowing term
We now show the key result of this section, that a charge spectrum `x` is in `minimallyAllowsTermsOfFinset S5 S10 T` if and only if it minimally allows the term `T`, provided it is in `ofFinset S5 S10`.
C. Other properties of `minimallyAllowsTermsOfFinset`
We show two other properties of `minimallyAllowsTermsOfFinset`.
C.1. Monotonicity of `minimallyAllowsTermsOfFinset` in allowed sets of charges
C.2. Not phenomenologically constrained if in `minimallyAllowsTermsOfFinset` for topYukawa
We show that every term which is in `minimallyAllowsTermsOfFinset S5 S10 topYukawa` is not phenomenologically constrained.

A spectrum is "minimal" if it contains exactly the number of fields required by the interaction and satisfies the selection rule (the weighted sum of charges is zero). The selection rules for each potential term are: - : such that . - : and such that . - : and such that . - : and such that . - : and such that . - : and such that . - : and such that . - : and such that . - : and such that . - : and such that . - : , and such that . In each case, fields not mentioned in the selection rule are assigned empty charge sets or `none`.
