%0 Journal Article %T Cartesian Products of Family of Real Linear Spaces %A Hiroyuki Okazaki %A Noboru Endou %A Yasunari Shidama %J Formalized Mathematics %@ 1898-9934 %D 2011 %I %R 10.2478/v10037-011-0009-2 %X In this article we introduced the isomorphism mapping between cartesian products of family of linear spaces [4]. Those products had been formalized by two different ways, i.e., the way using the functor [:X, Y:] and ones using the functor "product". By the same way, the isomorphism mapping was defined between Cartesian products of family of linear normed spaces also. %U http://versita.metapress.com/content/e35587t23865134j/?p=25816f9e6d274cf5ab90abc2a2c39abd&pi=8
