A Geometric Characterization of Steady Laminar Flow

Communications on Pure and Applied Mathematics, EarlyView.
ABSTRACT We study the steady states of the Euler equations on the periodic channel or annulus. We show that if these flows are laminar (layered by closed non‐contractible streamlines which foliate the domain), then they must be either parallel or circular flows.

Economic Stagnation and the Stagnation of Economics

Monthly Review, 1971
The New York Times carried a page-one, column-eight story in its issue of March 6th under the headline, "Rate of Jobless Fell in February for a 2nd Month."
