    Let \({\mathcal S}_{1/2}^{1}\) be a space of functions with standard topology, and let \(({\mathcal S}_{1/2}^{1})'\) be a space of all linear continuous functionals on space \({\mathcal S}_{1/2}^{1}\) with the weak topology. The author obtains the following analytical representation. If \(F\in ({\mathcal S}_{1/2}^{\beta})',\) then \(\forall \phi\in {\mathcal S}_{1/2}^{\beta}\): NEWLINE\[NEWLINE\langle F,\phi\rangle= \lim\limits_{\varepsilon\to 0+}\int\limits_{-\infty}^{\infty} [F_{\delta}^{*}(x+i\varepsilon)-F_{\delta}^{*}(x-i\varepsilon)] \exp(\delta x^{2})\phi(x) dx,NEWLINE\]NEWLINE where \(\delta\) depends on \(\phi\); \(F_{\delta}^{*}(z)\) is an indicatrix of the generalized function \(F\). Using this representation the sufficient condition for the localization principle in the space \(({\mathcal S}_{1/2}^{1})'\) is established.
