Did Thomas Pynchon publish a novel under the pseudonym Adrian Jones Pearson?

Interesting Pynchonesque Pynchon theory over at Harper’s today: Art Winslow plays with the idea that Thomas Pynchon published a novel called Cow Country under the pseudonym Adrian Jones Pearson. First two paragraphs:

Is it possible that the literary sensibility—person—that produced a clutch of novels under the name Thomas Pynchon has had a fat new novel out since April, under a different name, only to encounter a virtual vacuum of notice? That relative anonymity may have been expected, or might even have been among its aspirations, to prove a point?

Yes and yes. The book in question is called Cow Country, a 540-pager that came out of the chute from Cow Eye Press, a publishing house (if that is what it is) established in 2014 apparently for the express purpose of issuing Cow Country and perhaps related follow-ons, one of which is a centennial reprint of a 1916 eugenicist tract by Madison Grant, tying Americanism—patriotism—to racial purity. (Surely that is a stunt up someone’s sleeve.) Cow Eye Press sports a street address in Cheyenne, Wyoming, that is occupied by a registrar agent for company incorporation in the state, a firm that offers virtual offices in a locale “known for business-friendliness and respect for privacy.”
