Stable asymmetric states may be induced in catalytic wires controlled to attain a preset average temperature by changing the current fed into it. Complex multiplicity patterns are found there even at a fixed average temperature. A single-valued rate expression induces two bistability domains in a uniform wire. Cooling effects at the wire edge may eliminate one of these domains. Apparent isothermal tristability may be found with a multivalued rate curve but boundary effects destroy one of the solutions. Review of published multiplicity patterns observed with catalytic wires shows that isolated branches are due to the asymmetry.
