Dowker attended Manchester High School for Girls. [9] As a student, she was interested in wormholes and quantum cosmology.Having studied the Mathematical Tripos at the University of Cambridge, Dowker was awarded the Tyson Medal in 1987 and completed her Doctor of Philosophy for research on spacetime wormholes supervised by Stephen Hawking [2] [3] in 1990.
An ongoing task is to develop the correct dynamics for causal sets. These would provide a set of rules that determine which causal sets correspond to physically realistic spacetimes. The most popular approach to developing causal set dynamics is based on the sum-over-histories version of quantum mechanics. This approach would perform a sum-over ...

Causal decision theory of evaluating the expected utility of an action; Causal sets theory, an approach to quantum physics; Causal perturbation theory, a mathematically rigorous approach to renormalization theory; Causal theories, a phenomenon in social psychology whereby humans guess wrongly about the reasons for their actions (part of the ...
Consequently, the Lagrangian of CDT is constrained by the initial assumptions to the extent that it can be written down explicitly and analyzed (see, for example, hep-th/0505154, page 5), whereas there is more freedom in how one might write down an action for causal-set theory.
Judea Pearl defines a causal model as an ordered triple ,, , where U is a set of exogenous variables whose values are determined by factors outside the model; V is a set of endogenous variables whose values are determined by factors within the model; and E is a set of structural equations that express the value of each endogenous variable as a function of the values of the other variables in U ...

In mathematical logic, an alternative set theory is any of the alternative mathematical approaches to the concept of set and any alternative to the de facto standard set theory described in axiomatic set theory by the axioms of Zermelo–Fraenkel set theory.
