prepositional adjuncts

[Javier García Bonifaz]

Hi, everybody.

Does anybody know of some work done on prepositional adjuncts? I mean noun
phrases such as "the discovery of America" / "the discovery of Columbus".
In particular I'm interested in the possibility of treating prepositional
phrases as if their head were the noun phrase, i.e. "of America" --> head:
America, and considering the preposition as a mere case marker. If there's
some work done on HPSG for Spanish I would be interested in that too.

Thanks in advance,

Javier García
