A cognitive basis for physical time
Per Östborn
The treatment of time in relativity does not conform to that in quantum theory. In the context of quantum gravity this is called "the problem of time". A crucial difference is that…

Generally covariant evolution equations from a cognitive treatment of time
Per Östborn
The treatment of time in relativity does not conform to that in quantum theory. To resolve the discrepancy, a formalization of time is introduced in an accompanying paper, starting…

Renormalization of Oscillator Lattices with Disorder
Per Ostborn
A real-space renormalization transformation is constructed for lattices of non-identical oscillators with dynamics of the general form $dϕ_{k}/dt=ω_{k}+g\sum_{l}f_{lk}(ϕ_{l},ϕ_{k})…
