Surface Fitting is useful to researchers in fields from engineering to medicine. The expertise of mathematicians is needed to help with the analysis of data to help the experts in those fields draw appropriate conclusions. The research that this...
Let X and Z be topological spaces and Y be a subspace of X. A con-
tinuous function f : Y ! Z is extendable to X if there exists a continuous
function f : X ! Z such that f(x) = f(x) for all x 2 Y . If every continuous
function f : Y ! Z is...
