Ghastliness in mathematics

A good number of very high profile philosophers and mathematicians have drawn attention to what they see as the intrinsic beauty in mathematical solutions. Not so often mentioned, however, is that where there is beauty there can also be ugliness – or worse. For instance, take as an example the paper : ‘A GHASTLY GENERALIZED n-MANIFOLD’- by professor Robert J. Daverman and Dr. John J. Walsh (published in the ILLINOIS JOURNAL OF MATHEMATICS, Volume 25, Number 4, Winter 1981)

Our less mathematically gifted readers may not find the ghastliness immediately apparent though, indeed the word ‘ghastly’ appears only in the title of the paper, and thus at the risk of irritating those who are familiar with 2-ghastly spaces in acyclic manifold cell-like decompositions, and who will no doubt find the inherent ghastliness to be self-evident, we reprint below a concise explanation that Professor Daverman has kindly supplied to Improbable.

“It is ghastly because it contains no cuber of dimension 2, 3 …, or  n-1, where  N  is the dimension of the ghastly object.”
