Resumen
In this paper we show that Ultradistributions of Exponential Type (UET) are appropriate for the description in a consistent way string and string field theories. A new Lagrangian for the closed string is obtained and 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.
