deren

1. (relative) whose, of which (genitive of die, both inflected forms of der).
2. (demonstrative) her, their, the latter's (genitive of die, both inflected forms of der)

Among unexercised users of formal standard German, one can frequently read or hear dessen when deren would be correct (or occasionally vice versa), since neither of these forms is used in normal vernacular German.

Consider:

1. Sie haben ihre Freunde und ihren Sohn eingeladen.

   They have invited their friends and their son.

and

1. Sie haben ihre Freunde und deren Sohn eingeladen.

   They have invited their friends and their son.

The first sentence relates that the family which invites has a son, thus, they invite friends and that son. In the second sentence, the family invites their friends and a son of the invited family. Compare this behaviour with Russian свой and Russian possessive pronouns.
