Precisely, an isomorphic embedding j: E → X is said to be (linearly) 2-exact if bilinear forms on E can be (linear and continuously) extended to X through j . We present some necesary and some sufficient conditions for an embedding j: E → X to be 2-exact when X is an L1 -space.engjournal articlehttp://www.acadsci.fi/mathematica/Vol27/castillo.pdfhttp://www.acadsci.fi/mathematica/open access517.982.22Análisis funcional y teoría de operadores
