This is a list of things named for the British scientist Roger Penrose:
Mathematics Moore–Penrose inverse, the most widely known generalization of the inverse matrix in particular linear algebra Penrose graphical notation, a visual depiction of multilinear functions or tensors Penrose stairs, impossible object (co-created with his father Lionel Penrose) Penrose tiling, an example of an aperiodic tiling Penrose triangle, impossible object (co-created with his father Lionel Penrose) Penrose unilluminable room, first solution to the illumination problem
Physics Diósi–Penrose model, possible solution to the measurement problem Geroch–Held–Penrose formalism Newman–Penrose formalism, a set of notation for general relativity Penrose diagram, a two-dimensional diagram capturing the causal relations between different points in spacetime Penrose inequality, estimation of the mass of a spacetime Penrose conjecture Penrose interpretation, speculation about the relationship between quantum mechanics and general relativity Penrose process, or Penrose mechanism, a theoretical means whereby energy can be extracted from a rotating black hole Penrose singularity theorem in general relativity Penrose transform, a complex analogue of the Radon transform in theoretical physics Penrose–Terrell effect, visual distortion according to the special theory of relativity Penrose–Ward correspondence Rietdijk–Putnam–Penrose argument, version of Rietdijk–Putnam argument
Other Penrose–Lucas argument, a logical argument Penrose tennis ball, 1995, a novel economical design in which the two halves that cup to form the ball very nearly tile the plane.
