A Sturmian separation theorem for symplectic difference systems
We establish a Sturmian separation theorem for conjoined bases of 2n-dimensional symplectic difference systems. In particular, we show that the existence of a conjoined basis without focal points in a discrete interval (0,N...

Discrete quadratic functionals with jointly varying endpoints via separable endpoints
A characterization of the positivity of a discrete quadratic functional with mixed state endpoints is presented. The functional is transformed in two different ways into problems with separable endpoints to which previous results are applied. The out...

Personal Identity and the Conjoined Twinning Problem.
In the lecture I assess the charge that animalism leads to implausible consequences in analysing conjoined twinning cases. I evaluate a response by some proponents of animalism and show that the response fails....
