There is a gap between two different modes of computation: the
symbolic mode and the subsymbolic (neuron-like) mode. The aim of this
paper is to overcome this gap by viewing symbolism as a high-level
description of the properties of (a class of) neural networks.
Combining methods of algebraic sem...

The relation between music and motion has been a topic of much
theoretical and empirical research. An important contribution is made
by a family of computational theories, so-called kinematic models,
that propose an explicit relation between the laws of physical motion
in the real world and expre...

Installation art offers questions in stead of answers. Can a visual
artist generate meaning making installations in a world that is
dynamic, complex and instable? In the quest for an answer philosophy
can direct us towards conceptual questions that are raised by
installation art. In this way w...

The most widely used attractive logical account of knowledge uses
standard epistemic models, i.e., graphs whose edges are
indistinguishability relations for agents. In this paper, we discuss
more general topological models for a multi-agent epistemic language,
whose main uses so far have been in ...

This paper generalizes existing connections between automata and logic
to a coalgebraic level.
Let F be a standard endofunctor on Set that preserves weak pullbacks.
We introduce various notions of F-automata, devices that operate on
pointed F-coalgebras. The criterion under which such an automat...

A characteristic feature of infinitary combinatorics under the Axiom
of Determinacy is the existence of sequences of partition cardinals,
called Kleinberg sequences. It is well known that there are lots of
Kleinberg sequences below aleph-(epsilon-0), but the exact values of
their elements is stil...

This paper provides an update semantics for counterfactual
conditionals. It does so by giving a dynamic twist to the `Premise
Semantics' for counterfactuals developed in the late seventies. It
also offers an alternative solution to the problems with naive Premise
Semantics discussed by Angelika K...

Spencer's heritage, while almost a forgotten chapter in the history of
biology, lives on in psychology and the philosophy of mind. I
particularly discuss externalist views of meaning, on which meaning
crucially depends on a notion of reference, and ask whether reference
should be thought of as ca...

In this paper we present a model for games with perfect information in
which the players, upon observing an unexpected move, may revise their
beliefs about the opponents' preferences over outcomes. For a given
profile P of preference relations over outcomes, we impose the
following three principl...
