On surjective linear maps preserving commutativity
Proceedings of the Royal Society of Edinburgh: Section A Mathematics, 2004We describe surjective linear maps preserving commutativity from (symmetric elements of) any algebra (with involution) onto (symmetric elements of) a prime algebra (with involution) not satisfying polynomial identities of low degree. Bijective commutativity preservers on skew elements of centrally closed prime algebras with involution of the first kind

Commutative semifields from projection mappings
Designs, Codes and Cryptography, 2010Let \(q\) be a power of the odd prime \(p\), \(m\) an odd natural number, and let \(F\) be the field with \(q^{2m}\) elements. Sitting inside \(F\) are the fields \(F_q\), \(K\), \(L\), with \(q\), \(q^2\), \(q^m\) elements, respectively. For any map \(f: F\to F\) define the polarization \(x\ast y:=(f(x+y)-f(x)-f(y))/2\). Then \(f\) is called planar if
