I can understand the authors are unhappy with the inept typesetting of the unauthorized publication. Apart from the name issue, a whole set of problems hurt the eye, that could have been avoided with an appropriate typesetting software such as LaTeX:
- Hyphen errors such as “discussed in de- tail below.”
- Missing spaces as in “examined.In particular,”
- Wrong equation numbering: (3a) appears twice and there are references to missing equation (4).
- No consistency in mathematical mode: Displays use different fonts as mathematical symbols in the text, and sizes do not match; indices are sometimes italicized and sometimes not (as they should); the placement of indices is awkard and sizes are not consistent.
- Quotation marks are not used consistently.
- Accents are missing in the references, e.g. Csiszar I.
- In addition, every basic typesetting manual will tell you that mixing fonts with and without serifs is not considered the best of practices.
