In the early hours of 7 May 1837, after Hogarth had returned from a showing of "Is She His Wife?" at the St James's Theatre with the Dickens couple, she collapsed
Arrangement of lines of the circle as a Klein model of the hyperbolic plane). However, in hyperbolic line arrangements lines may avoid crossing each other without being parallel; the intersection graph of the lines in a hyperbolic arrangement is a circle graph. The corresponding concept to hyperbolic line arrangements for pseudolines is a "weak pseudoline arrangement", a family of curves having the same topological properties as lines such that any two curves in the family either meet in a single crossing point or have no intersection. Arrangement of lines In geometry an arrangement of lines is the partition of the plane formed by
