摘要

在 [U. Dempwolff: \textit{More Translation Planes and Semifields from Dembowski-Ostrom Polynomials}, Designs, Codes, Cryptogr. \textbf{68} (1-3) (2013), 81--103] 中,展示了三类阶为 q2nq^{2n}(其中 qqnn 为奇数)的秩 2 预半域,但其同位素问题仍悬而未决。在 [M. Lavrauw, G. Marino, O. Polverino, R. Trombetti: \textit{Solution to an isotopism question concerning rank 2 semifields}, J. Comb. Des., to appear. DOI: 10.1002/jcd.21382] 中,作者探讨了这一问题,回答了当 n>3n>3 时这些预半域是否为新构型的问题。本文完成了该项研究,解决了 n=3n=3 的情形。
