Manuscripts should be submitted by e-mail to the journal office. Each paper should be accompanied by an abstract and should bear the five-character Mathematics Subject Classification Code (MSC 2020). Key words are optional, but desirable. Manuscripts are accepted for review with the understanding that the same work has not been and will not be published elsewhere, nor is presently submitted elsewhere, and that all persons listed as authors have given their approval for the submission of the paper.

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.

Only standard abbreviations for names of journals (see Zentralblatt MATH) should be used in references.

Please prepare your manuscript in AMS-LaTeX (template, with detailed instructions, can be downloaded from here) name your files by your name(s), and send figures/illustrations as eps files (each figure/illustration in a separate file).
