Angsheng Li: Priority Arguments I, II, and III.

I. Basic constructions of finite, infinite, and 0'''-priority tree construction

This talk is on finite injury, novel infinite injury, and basic 0'''
arguments.

II. Advanced 0'''-priority tree constructions

This is on nonsplitting constructions.

III. Local Turing degrees

The new features of non-c.e. degrees, and the power of the priority
arguments in the non-c.e. area.
