Harry Potter and the Meaning of Death

The paper reviews how J.K. Rowling is able to examine death in the Harry Potter book series. In the first part of the text the author touches on the deaths of Harry\u27s parents and the scarring that Harry receives from that, as well as an examination of how the deaths of others, from close friends to acquaintances, have affected Harry, specifically pertaining to his personal responsibility for them and also his grieving process. The paper also goes into how Voldemort\u27s inability to feel love, paired with his fear of dying, have pushed his quest for immortality (using Horcruxes). Harry\u27s mastery of death (using the Hallows), his willingness to accept death, and his sense of love and sacrifice for his friends is what enables him to finally defeat Voldemort. The main message is that the Harry Potter books are great entertainment, but their underlying philosophy on death creates a depth that Rowling wants us to learn from: death is a part of life, and seeking love and friendship is much more important than worrying about death

Bi-Hamiltonian Aspects of a Matrix Harry Dym Hierarchy

We study the Harry Dym hierarchy of nonlinear evolution equations from the bi-Hamiltonian view point. This is done by using the concept of an S-hierarchy. It allows us to define a matrix Harry Dym hierarchy of commuting Hamiltonian flows in two fields that projects onto the scalar Harry Dym hierarchy. We also show that the conserved densities of the matrix Harry Dym equation can be found by means of a Riccati-type equation.Comment: Revised version, 22 pages; a section on reciprocal transformations added.

Book review: the books that inspired Harry Goulbourne: “Fanon’s black skin, white masks suggested that I attended to the question of who I was”

Harry Goulbourne has written many books on race relations and ethnicity and identity. Harry talks us through his fragmented school days in South London, how his engagement in student politics drove his interest in American History, and how the work of Frantz Fanon had a big impact on how he thought about himself

Supersymmetric Reciprocal Transformation and Its Applications

The supersymmetric analog of the reciprocal transformation is introduced. This is used to establish a transformation between one of the supersymmetric Harry Dym equations and the supersymmetric modified Korteweg-de Vries equation. The reciprocal transformation, as a B\"{a}cklund-type transformation between these two equations, is adopted to construct a recursion operator of the supersymmetric Harry Dym equation. By proper factorization of the recursion operator, a bi-Hamiltonian structure is found for the supersymmetric Harry Dym equation. Furthermore, a supersymmetric Kawamoto equation is proposed and is associated to the supersymmetric Sawada-Kotera equation. The recursion operator and odd bi-Hamiltonian structure of the supersymmetric Kawamoto equation are also constructed.Comment: 31 pages, expande

On bosonic limits of two recent supersymmetric extensions of the Harry Dym hierarchy

Two generalized Harry Dym equations, recently found by Brunelli, Das and Popowicz in the bosonic limit of new supersymmetric extensions of the Harry Dym hierarchy [J. Math. Phys. 44:4756--4767 (2003)], are transformed into previously known integrable systems: one--into a pair of decoupled KdV equations, the other one--into a pair of coupled mKdV equations from a bi-Hamiltonian hierarchy of Kupershmidt.Comment: 7 page
