Abstract
We show that stable localized solutions of square symmetry and a numbe r of different sizes are possible in a model equation for pattern-form ing nonequilibrium systems. We point out that these localized solution s, which are surrounded by a pattern-free state, exist for a range of values for the external stress parameter subcritically. We discuss bri efly for which experimentally accessible systems such states could pos sibly be observable.
