Hierarchical Unambiguity

open access: yesLecture Notes in Computer Science, 2006
We develop techniques to investigate relativized hierarchical unambiguous computation. We apply our techniques to generalize known constructs involving relativized unambiguity based complexity classes (UP and \mathcal{UP}) to new constructs involving arbitrary higher levels of the relativized unambiguous polynomial hierarchy (UPH).

On the Power of Unambiguity in Alternating Machines

open access: yesLecture Notes in Computer Science, 2005
Unambiguity in alternating Turing machines has received considerable attention in the context of analyzing globally-unique games by Aida et al. [ACRW04] and in the design of efficient protocols involving globally-unique games by Crâsmaru et al. [CGRS04].

Making nondeterminism unambiguous

Proceedings 38th Annual Symposium on Foundations of Computer Science, 2000
Summary: We show that in the context of nonuniform complexity, nondeterministic logarithmic space bounded computation can be made unambiguous. An analogous result holds for the class of problems reducible to context-free languages. In terms of complexity classes, this can be stated as \[ \begin{aligned} \text{NL/poly} &= \text{UL/poly},\\ \text{LogCFL ...

Unambiguous Functions in Logarithmic Space [PDF]

open access: possibleFundamenta Informaticae, 2012
We investigate different variants of unambiguity in the context of computing multi-valued functions. We propose a modification to the standard computation models of Turing machines and configuration graphs, which allows for unambiguity-preserving composition.

'If' is Unambiguous

Noûs, 1987
Recently, Allan Gibbard has argued that there is a semantic difference between indicative and subjunctive conditional sentences. His arguments, which derive in part from the work of E.W. Adams (see [1] and [2] for example), are presented in detail in [3].
