Then, according to Conditional Reflexivity, each location is exactly located at itself.
If one is an endurantist, one will find it natural to describe this situation as involving multi-location in space or spacetime: Suzy is exactly located at rA, a region with the size and shape of an adult; Baby Suzy is exactly located at rB, a disjoint but simultaneous region with the size and shape of a baby; and Suzy=Baby Suzy.
Some of them might prefer to say that a monadic universal is exactly located only at the sum of the exact locations of its instances (Bigelow, 1988: 18 27, can in places be read as embracing this).
The locational endurantist will say that the object is exactly located at many regions, each of them a slice of its path.
(See also Donnelly (2004: 158), who presents a system in which Conditional Reflexivity is a theorem, though she replaces the location predicate 'L' with a primitive function symbol 'r' for 'the exact location of'.) Let a location be an entity at which something is exactly located.
One might then define exact location in terms of it, as follows: 'x is exactly located at y' means 'for any z, if z is simple, then: z lies within x if and only if z is a part of y'.
Simulations are performed to reproduce the stationary "EIT wave" front, which is exactly located near the footpoint of the magnetic separatrix, consistent with observations.
Then given Weak Expansivity, rh is a part of rb, and given Conditional Reflexivity, rh is exactly located at rh, and rb is exactly located at rb.
It is exactly located at the circular region r3; and it is exactly located at the circular region r4, which does not overlap r3.
Together with Conditional Reflexivity, (DR) entails that that if x is exactly located at y, then y is exactly located at itself and hence is a region.
Not the fact that o1 has P and is exactly located at r1.
