topology
  توپوشناسی  
topošenâsi
Fr.: topologie  

The study of the properties of geometric figures that remain invariant under certain transformations, as bending or stretching. A circle is topologically equivalent to an ellipse (into which it can be deformed by stretching) and a sphere is equivalent to an ellipsoid.

Etymology (EN): From topo- combining form of Gk. topos “place”

Etymology (PE): Topošenâsi, from topo-, loan from Gk., as above, + šenâsi→ -logy.
