Stephen Hawking's final paper that he and his colleagues completed just days before his death has now been published. It's titled "Black Hole Entropy and Soft Hair," co-authored with Sasha Haco, Malcolm J. Perry, and Andrew Strominger, about the black hole information paradox. Here is the abstract:
A set of infinitesimal VirasoroL⊗VirasoroR diffeomorphisms are presented ... Reading the I Ching involves casting coins or yarrow stalks (yarrow is a type of flowering plant with flat flowerheads and lacy leave) to build six lines called a hexagram. ... Elliptical galaxies are ellipsoidal agglomerations of stars, which usually do not contain much interstellar matter, and look smoothly like small wads when viewed through a telescope. ...Physicists Pin Down the Nuclear Reaction After the Big Bang
