Spirit of the Dead Watching her fear. Mathews says it is too simple to attribute Tehura's terror to her belief in spirits and irrational fear of the dark; she says, following Sweetman, that Gauguin's sexual predilections should not be ignored when trying to understand the work. Rather, she suggests the girl's fear was a response to Gauguin's aggressive behavior, consistent with his known battering (so says Mathews) of his wife Mette, the submissive fear in her eyes his erotic reward. Stephen F. Eisenman, professor of Art History at Northwestern University, suggests the painting and its narrative is "a veritable encyclopaedia of colonial racism and misogyny".
Irrational rotation ergodic transformation, but it is not mixing. The Poincaré map for the dynamical system associated with the Kronecker foliation on a torus with angle is the irrational rotation by . C*-algebras associated with irrational rotations, known as irrational rotation algebras, have been extensively studied. Irrational rotation In the mathematical theory of dynamical systems, an irrational rotation is a map where "θ" is an irrational number. Under the identification of a circle with R/Z, or with the interval [0, 1] with the boundary points glued together, this map becomes a rotation of a circle by a proportion "θ" of a full
