Stationary solutions of bistable reaction-diffusion equations on some thin tubular domain
Abstract:
On a thin tubular domain, we consider a scalar bistable reaction-diffusion equation
with the Neumann boundary condition. The domain is given as a tubular neighborhood
of a line segment such that the middle part is much thinner than the other part.
Since the domain is close to a line segment, the equation is expected to be approximated
by some one-dimensional limiting equation. After formally deriving the appropriate limiting equation,
we show that it indeed approximates the original equation.
Then we consider the solution structure of the limiting equation.
