Simplified Modelling of a Thermal Bath, with Application to a Fluid Vortex System
Based on the thermodynamic concept of a reservoir, we investigate a computational model for interaction with unresolved degrees of freedom (a thermal bath). We assume that a finite...

Algebras Versus Coalgebras
Algebras and coalgebras are fundamental notions for large parts of mathematics. The basic constructions from universal algebra are now expressed in the language of categories and ...

A New Derandomization of Auctions
Let A be a randomized, unlimited supply, unit demand, single-item auction, which given a bid-vector b ∈ [h]n , has expected profit E[P(b)]. Aggarwal et al. showed that given A, ...

Hierarchical morse complexes for piecewise linear 2-manifolds
We present algorithms for constructing a hierarchy of increasingly coarse Morse complexes that decompose a piecewise linear 2-manifold. While Morse complexes are defined only in t...

Symbolic models for control systems
In this paper we provide a bridge between the infinite state models used in control theory to describe the evolution of continuous physical processes and the finite state models ...
