Tests for the existence of black holes through gravitational wave echoes
Nature Astronomy, 2017The existence of black holes and spacetime singularities is a fundamental issue in science. Despite this, observations supporting their existence are scarce, and their interpretation is unclear.

Nonlinear normal modes and spectral submanifolds: existence, uniqueness and use in model reduction
, 2016We propose a unified approach to nonlinear modal analysis in dissipative oscillatory systems. This approach eliminates conflicting definitions, covers both autonomous and time-dependent systems and provides exact mathematical existence, uniqueness and ...

Frege on Existence and Non‐existence
Theoria, 2015AbstractDespite its importance for early analytic philosophy, Gottlob Frege's account of existence statements, according to which they classify concepts, has been thought to succumb to a number of well‐worn criticisms. This article does two things. First, it argues that, by remaining faithful to the letter of Frege's claim that concepts are functions ...

Beyond Existence and Non-Existence
International Journal of Philosophical Studies, 2013Abstract When Husserl speaks of the so-called ‘transcendental reduction’ or ‘phenomenological epochē’ many believe that he is eschewing the question of truth or existence. Two reasons are given for this: First, Husserl explicitly states that when we perform the reduction, we should no longer naively ‘accept [the world] as it presents itself to me as ...

The Philosophical Quarterly, 2006
I compare the theory of existence and being (and of non-existence and non-being) presented in Colin McGinn's Logical Properties with those of well known predecessors such as Quine, Frege and Meinong. More recently, neo-Meinongians have held that being and existence are different concepts, and that although nothing lacks being, there are things which do

The Existence of Tricyanomethane
Angewandte Chemie International Edition, 2015AbstractCalcium tricyanomethanide reacts with hydrogen fluoride under formation of tricyanomethane and Ca(HF2)2. Tricyanomethane is stable below −40 °C and was characterized by IR, Raman, and NMR spectroscopy. The vibrational spectra were compared to the quantum‐chemical frequencies at the PBE1PBE/6‐311G(3df,3dp) level of theory and confirm the ...

There’s no existent like ‘no existence’ like no existent I know
Philosophical Studies, 2009The aim of this paper is to motivate and then defend a restricted version of the truth-maker theory. In defending such a theory I hope to do away with the perceived need for ‘negative existents’ such as totality facts and the like.

On the Partial Existence of Existing and Non-existing Objects
2000The paper tries to find an intermediary zone between metaphysics - especially that of Whitehead- and sociology or social history of science. It offers a sketchy but robust vocabulary to define the spatio-temporal envelop of phenomena, without having to take decisions on their existence or non-existence.
