Description: A multi-purpose center for electronic distribution of information related to topology, the mathematical study of surfaces, sometimes called "rubber sheet geometry" because topologists consider geometric figures as though they were drawn on infinitely stretchable rubber sheets. In two dimensions, topologists imagine figures that can be stretched and pulled as though they were drawn on an infinitely thin, infinitely stretchable material that can be deformed in any way (not including tearing, perforating, or gluing). Some properties that are important in Euclidean geometry such as distance, measurement of angles, or straightness, don't hold. Other properties, such as whether lines intersect or whether figures are closed (like the letter "O" ) or open (like the letter "U") remain important. Includes Knot Theory.
