We consider   bivariate  mean-value interpolationproblem, where the integrals over circles are interpolation data. In this case the problem  is described  over   circles of the same radius and with  centers are on astraight line and it is shown that in this case the interpolation is not correct.

Fuzzy Topological Topographic Mapping (FTTM) is a mathematical model that consists of set homeomorphic topological spaces designed to solve the neuro magnetic inverse problem. A sequence FTTM, denoted as FTTMn, an extension FTTM arranged in symmetrical form. The special characteristic namely homeomorphisms between its components, allows generation new FTTM. Later, FTTMn can also be viewed graph...
