BibTeX loses capitals when creating .bbl file

I have a .bib file and I'm using JabRef to edit it.

Its content is

% This file was created with JabRef 2.7b.
% Encoding: UTF-8

@ARTICLE{adem,
  author = {Alejandro Adem and William Browder},
  title = {The free rank of symmetry of $(S^n)^k$},
  journal = {Inventiones Mathematicae},
  year = {1988},
  volume = {92},
  pages = {431--440}
}

but when I run bibtex and compile my file the title is strange since the math symbols were shown in lower case. Instead of The free rank of symmetry of $(S^n)^k$ it shows The free rank of symmetry of $(s^n)^k$ (note the small s).

I'm using \bibliographystyle{plain}.

Any help?

The bibliography style you are using sets only the first letter of a title in uppercase and converts everything else to lowercase.
To protect parts of a title from this, encase them in curly brackets {} in the .bib file, e.g.

@ARTICLE{adem,
  author = {Alejandro Adem and William Browder},
  title = {The free rank of symmetry of {$(S^n)^k$}},
  journal = {Inventiones Mathematicae},
  year = {1988},
  volume = {92},
  pages = {431--440}
}
