The construction of coarse spaces for irregular decompositions, as the ones obtained from mesh partitioners, usually involve functions that are discrete harmonic in the interior of the subdomains. In this talk we will discuss a variant used in the definition of coarse spaces for such irregular decompositions based on the virtual element method, that does not require discrete harmonic extensions and saves computational time. Theoretical results and numerical experiments that verify the results will be discussed.
