Approximation of the singularity coefficients of an elliptic equation by mortar spectral element method
In a polygonal domain, the solution of a linear elliptic problem is written as a sum of a regular part and a linear combination of singular functions multiplied by appropriate coefficients. For computing the leading singularity coefficient we use the dual method which based on the first singular...
