Abstract

Let E be an arbitrary space, and 驴 an extensive dilation of P(E) into itself, with an adjoint erosion 驴. Then, the image 驴[P(E)] of P(E) by 驴 is a complete lattice P where the sup is the union and the inf the opening of the intersection according to 驴 驴. The lattice L, named viscous, is not distributive, nor complemented. Any dilation 驴 on P(E) admits the same expression in L. However, the erosion in L is the opening according to 驴 驴 of the erosion in P(E). Given a connection C on P(E) the image of C under 驴 turns out to be a connection C 驴 on L as soon as 驴 驴 (C)驴eq C. Moreover, the elementary connected openings 驴x of C and 驴驴驴(x) are linked by the relation 驴驴驴(x) = 驴驴x驴. A comprehensive class of connection preverving closings 驴 驴 is constructed. Two examples, binary and numerical (the latter comes from the heart imaging), prove the relevance of viscous lattices in interpolation and in segmentation problems.
