Unwinding the Black Hole Entropy in a Noncommutative Space
Comments: 16 pages, 4 figures, v4: refs added

We consider a noncommutative space in which the positivity condition is violated, but the cosmological constant (Coulomb degree of freedom) is precisely equal to the Planck mass. The entropy of the black hole is investigated in this noncommutative space. We find that the black hole entropy is equivalent to the kinetic term of the black hole. We also discuss the relation between the black hole entropy and the entropy of the observer. We find that the black hole entropy is proportional to the entropy of the observer.
