We consider the TRS containing the following rules:

The underlying signature is as follows:

Property / Task

Answer / Result

Proof (by csi @ CoCo 2023)

1 Redundant Rules Transformation

To prove that the TRS is (non-)confluent, we show (non-)confluence of the following modified system:

All redundant rules that were added or removed can be simulated in 3 steps .

1.1 Redundant Rules Transformation

To prove that the TRS is (non-)confluent, we show (non-)confluence of the following modified system:

All redundant rules that were added or removed can be simulated in 1 steps .

1.1.1 Redundant Rules Transformation

To prove that the TRS is (non-)confluent, we show (non-)confluence of the following modified system:

All redundant rules that were added or removed can be simulated in 3 steps .
