Boundedness of completely additive measures with application to 2-local triple derivations

Jan Hamhalter, Karimbergen Kudaybergenov, Antonio M. Peralta +1

We prove a Jordan version of Dorofeev's boundedness theorem for completely additive measues and use it to show that every (not necessarily linear nor continuous) 2-local triple der…

Decompositions of preduals of JBW and JBW∗ algebras

Martin Bohata, Jan Hamhalter, Ondřej F. K. Kalenda

We prove that the predual of any JBW∗-algebra is a complex 1-Plichko space and the predual of any JBW-algebra is a real 1-Plichko space. I.e., any such space has a countably…
