Title: On intrinsic differentiability in the Wasserstein space P2(Rd)


Abstract: We elucidate the connection between different notions of 
differentiability in P2(Rd): some have been introduced intrinsically by 
Ambrosio–Gigli–Savaré, the other notion due to Lions, is extrinsic and 
arises from the identification of P2(Rd) with the Hilbert space of 
square-integrable random variables. We mention potential applications 
such as uniqueness of viscosity solutions for Hamilton-Jacobi equations 
in P2(Rd), the latter not known to satisfy the Radon–Nikodym property.
