Observer-Dependence in P vs NP
《Journal of Modern Physics》2025年第1期6-51,共46页Logan Nye 
We present a new perspective on the P vs NP problem by demonstrating that its answer is inherently observer-dependent in curved spacetime, revealing an oversight in the classical formulation of computational complexit...
