# Operator Classes


This page documents the operator classes used to describe an individual term $F_i$ in the inclusion problem. 

The set of operators are 
listed in {doc}`Operators <../../usage/problem_formulation/system/index_system>`. 


```{toctree}
:maxdepth: 1
Set-Valued Maps <doc_set_valued>
Subdifferentials <doc_sml>
Gradients of Quadratics <doc_quadratic>
``` 

## Common Routines

All operator classes share common routines:
```{eval-rst}
.. mat:autoclass :: operator.operator_interface  
    :members:
```
