Abstract snark

The abstracts for these two papers (one a classic in robust control theory, the other in mathematical physics) are almost Zen in their simplicity and perfection:

J. C. Doyle, “Guaranteed margins for LQG regulators,” IEEE Transactions on Automatic Control, vol. 23, no. 4, pp. 756-757, 1978

Abstract: There are none.

J. E. Avron, L. Sadun, J. Segert and B. Simon, “Chern numbers, quaternions, and Berry’s phases
in Fermi systems,” Communications in Mathematical Physics, vol. 124, pp. 595-627, 1989

Abstract: Yes, but some parts are reasonably concrete.

P.S. (More or less) regular blogging to resume in 3, 2, 1 … .
