Title	Pseudo Entropy in dS/CFT and Time-like Entanglement Entropy
Abstract	dS/CFT correspondence, a holographic duality for de Sitter gravity, has not been well understood compared to AdS/CFT. We study holographic entanglement entropy in dS/CFT and introduce time-like entanglement entropy in AdS/CFT. Both of them take complex values in general and are related with each other via an analytical continuation. Furthermore, we can give a holographic interpretation to the imaginary part of the time-like entanglement entropy as a time-like surface. We also argue that they are correctly understood as pseudo entropy.
