 Several projects in the Python ecosystem provide implementations of proximal operators and/or algorithms, 
 which present some overlap with those available in `PyProximal`. A (possibly not exhaustive) list of other projects is composed of
-*proxalgs* [@Maheswaranathan], *proxmin* [@Melchior], *The Proximity Operator Repository* [@Chierchia], *ProxImaL* [@Chan],

 are provided, but also linear operators that are useful for the applications that the package targets. Moreover, to the best of our knowledge, all of these packages
 provide purely CPU-based implementations (apart from *pyxu*). On the other hand, `PyProximal` heavily relies on and seamlessly integrates with `PyLops` [@Ravasi:2020], a Python library for matrix-free linear algebra 
 and optimization. As such, it can easily handle problems with millions of unknowns and inherits
