Effective Algebra and Effective Dimension

Effective Dimension is a notion introduced by Lutz, which measures the density of information in an infinite sequence. Lutz asks how this concept interacts with classical topological notions. In Chapter two, I present several results concerning this. Effective Algebra is the study of computable and relatively computable structures and the relations on them. In Chapter three, I present several r...

Towards effective simulation of effective elastoplastic evolution

This paper summarises the general strategy for time evolving finite elastoplasticity and outlines encountered computational challenges in form of numerical benchmarks. Each time-step of some natural implicit time-discretisation is eventually recast into a possibly non-convex minimisation problem. Finite plasticity seems to imply the lack of lower semicontinuity of the energy functional and so l...

Position Paper: Effective PKI Requires Effective HCI

PKI researchers keep producing applications that use publickey cryptography to enable human users (and service providers) to make effective trust judgments across organizational boundaries. However, too often, when we look closely, these judgments are unfounded; a moderately malicious adversary can often defeat the system. This position paper posits that this problem is endemic to current effor...

Effective β-functions for Effective Field Theory

We consider the problem of determining the beta-functions for any reduced effective field theory. Even though not all the Green’s functions of a reduced effective field theory are renormalizable, unlike the full effective field theory, certain effective beta-functions for the reduced set of couplings may be calculated without having to introduce vertices in the Feynman rules for redundant opera...
