INSTRUCTIONS FOR 
AUTHORS
Manuscripts should be submitted in three copies. They are 
expected not to exceed 16 printed pages. Each paper should be accompanied by an 
abstract and should bear the five-character AMS subject classification code 
(2000). 
Formulas should be displayed only if they must be enumerated for 
future reference or if they are too long or complicated. Please do not enumerate 
formulas which are not referred to. 
A new paragraph should not be 
started if this is not necessary. Paragraphs of one or two lines (one or two 
sentences) are possible, of course, but they should be exceptional, not usual. 
Only standard abbreviations for names of journals (see Zentralblatt 
MATH) should be used in references.
If you prepare your manuscript on a 
computer, then we suggest using TeX. If you prepare figures or illustrations on 
a computer, then please send them in a form of .PCX or .BMP file (each figure or 
illustration in a separate file). Make sure that they fit into the dimensions of 
the text of our journal (printed with resolution of 600 dpi).
