Title: Extended KP hierarchy and its two-dimensional reductions
Abstract: Conventionally, the KP hierarchy can be divided into several parts:

1. purely differential part (obtained from the compatibility conditions of differential operators);
2. pseudo-differential part (obtained from the compatibility conditions of pseudo-differential operators);
3. semi-discrete part (obtained from the compatibility conditions of differential and difference operators);
4. purely discrete part (obtained from the compatibility conditions of difference operators).

The restriction of these operators to the stationary case leads to two-dimensional reductions.
Thus, three-dimensional equations will be constructed from the KP hierarchy, as well as their two-dimensional reductions.
