e/Join (topology)

Information
has gloss	eng: In topology, a field of mathematics, the join of two topological spaces A and B, often denoted by A\star B, is defined to be the quotient space : (A \times B \times I) / R, \, where I is the interval [0, 1] and R is the relation defined by : (a, b_1, 0) \sim (a, b_2, 0) \quad\mboxfor all } a \in A \mbox and } b_1,b_2 \in B, : (a_1, b, 1) \sim (a_2, b, 1) \quad\mboxfor all } a_1,a_2 \in A \mbox and } b \in B. In effect, one is collapsing A\times B\times \0\} to A and A\times B\times \1\} to B.
lexicalization	eng: join
