Homework Help: Capital Lambda

  1. Nov 28, 2011 #1
    Does anyone know what [itex]\Lambda[/itex] means in the collection of elements:[tex]\{ A_{\lambda} : \lambda \in \Lambda\}[/tex]
    For example in the definition of a topology: if [itex]\{ A_{\lambda} : \lambda \in \Lambda\}[/itex] is a collection of elements of a topology then [itex]\bigcup _{\lambda \in \Lambda} A_{\lambda}[/itex] is in the topology.

    I believe [itex]\Lambda[/itex] is just a collection of indexes.
