The Wecken problem for coincidences of boundary preserving surface maps
We prove a Brooks type coincidence minimization result for boundary preserving maps on compact surfaces with boundary.
As an application we obtain non-boundary Wecken results for pairs of maps
$f,g\colon (X,\partial X) \to (X,\partial X)$ for most surfaces $X$.
期刊介绍:
Topological Methods in Nonlinear Analysis (TMNA) publishes research and survey papers on a wide range of nonlinear analysis, giving preference to those that employ topological methods. Papers in topology that are of interest in the treatment of nonlinear problems may also be included.
