Rd. Benguria et Mc. Depassier, ON THE EXISTENCE OF MONOTONIC FRONTS FOR A CLASS OF PHYSICAL PROBLEMSDESCRIBED BY THE EQUATION LAMBDA-W'''+W'=F(W), Journal of physics. A, mathematical and general, 27(4), 1994, pp. 1339-1344
We obtain an upper bound on the value of lambda for which monotonic fr
ont solutions of the equation lambdaw''' + w' = f(w) with lambda > 0 m
ay exist.
