VOLUNTARY DONATION FEE

The Parana’s Mathematics Society (SPM) is a non-profit organization. We charge annual fees from members once a year to pay employees' salaries, to pay the DOI (Digital Object Identifier) of published articles and  CrossRef annual fee. However, due to the significant increase in the dollar's value, we are experiencing difficulties in meeting the large demand for articles submitted and accepted for the Bulletin of Parana’s Mathematical Society (BSPM). In this way, we will ask each author who has an article accepted for publication a fee, in fact, a donation of twenty-five dollars (US$ 25) to help us keep BSPM publishing high-quality articles with a greater number of volumes per year. We usually publish one volume per year containing 150 articles. We aim to reach four volumes per year with the same number of articles. We kindly request this donation to support our efforts, but please note that it is entirely voluntary and will not affect the acceptance of your article for publication in BSPM. However, authors who donate will be given priority in the publication schedule as a token of our appreciation for their support.

We hope you understand,

Cordially,

Marcelo Cavalcanti  (Chief Editor)
