Resumen:
In this paper we show that Ultradistributions of Exponential Type(UET) are appropriate for the descriptionin a consistent way string and string field theories.A new Lagrangian for the closed string is obtainedand shown to be equivalent to Nambu-Goto´s Lagrangian. We also show that the string field is a linear superposition of UET of compact support CUET).We evaluate the propagator for the string field,and calculate the convolution of two of them.
