Scrabble?! TOPOLOGISTS

Definitions of TOPOLOGISTS in various dictionaries:

In the branch of mathematics known as topology, the topologist's sine curve or Warsaw sine curve is a topological space with several interesting properties that make it an important textbook example. It can be defined as the graph of the function sin(1/x) on the half-open interval (0, 1], together with the origin, under the topology induced from the Euclidean plane: T = { ( x , sin ⁡ 1 x ) : x ∈ ( 0 , 1 ] } ∪ { ( 0 , 0 ) } . {\displaystyle T=\left\{\left(x,\sin {\tfrac {1}{x}}\right):x\in (0,1]\right\}\cup \{(0,0)\}.}
