Group algebras whose groups of normalized units have exponent 4 Victor Bovdi; Mohammed Salim — 2018 Czechoslovak Mathematical Journal We give a full description of locally finite 2 -groups G such that the normalized group of units of the group algebra F G over a field F of characteristic 2 has exponent 4 .
