DESCRIPTION:We discuss applications of geometric current transforms to exp
 licit formulas for regulator maps into integral Deligne-Beilinson cohomolo
 gy\, utilizing Suslin's equidimensional cycles approach to higher Chow gro
 ups. This&nbsp\;regulator map presents surprisingly pleasant multiplicativ
 e properties at the level of complexes\, which are related to characters o
 f certain Hopf algebras.&nbsp\;
