Abstract
In Euclidean 3space endowed with a Cartesian reference system, we consider a class of surfaces, called Delaunay tori, constructed by bending segments of Delaunay cylinders with necksize a and n lobes along circumferences centered at the origin. Such surfaces are complete and compact, have genus one and almost constant, say 1, mean curvature, when n is large. Considering a class of mappings H: (Formula presented) (Formula presented) such that H(X) 1 as X (Formula presented) with some decay of inversepower type, we show that for n large and  a small, in a suitable neighborhood of any Delaunay torus with n lobes and necksize a there is no parametric surface constructed as normal graph over the Delaunay torus and whose mean curvature equals H at every point.
