We present a generalization of the mode-coupling theory of the glass transition to the case of a particle actively pulled by means of a time-and space constant external force. We predict such typical nonlinear effects like yielding (existence of a critical force needed to pull the particle free out of the cage of its nearest neighbors) and thinning (the decay of the friction coefficient with increasing external force). For the case of a hard sphere suspension, we succeeded to evaluate the value of the critical force, which is in semi-quantitative agreement with simulations and experiments. We present also simplified schematic versions of the microscopic equations of the theory, which retain some crucial properties of the whole equations, but are more easily treatable.</dcterms:abstract> <dcterms:isPartOf rdf:resource=""/> <dcterms:rights rdf:resource=""/> </rdf:Description> </rdf:RDF>
