However, in the present paper, the integrals $I(u)$ and $\mathfrak\{I\}(u)$ are reduced to simpler form $H(v)$ and $\mathcal\{H\}(v)$ to which the existence theorems above apply. Thus, we derive that $I(u) \le \mathfrak\{I\}(u)$, $H(v) \le \mathcal\{H\}(v)$, we obtain the existence of the absolute minimum for the Serrin forms $\mathfrak\{I\}(u)$ and $\mathcal\{H\}(v)$, and such minimum is given by BV functions, possibly discontinuous and not of Sobolev.},

AB - In the present paper the author discusses certain multiple integrals $I(u)$ of the calculus of variations satisfying convexity conditions, and no growth property, and the corresponding Serrin integrals $\mathfrak{I}(u)$, to which the existence theorems in [3,4,5] do not apply. However, in the present paper, the integrals $I(u)$ and $\mathfrak{I}(u)$ are reduced to simpler form $H(v)$ and $\mathcal{H}(v)$ to which the existence theorems above apply. Thus, we derive that $I(u) \le \mathfrak{I}(u)$, $H(v) \le \mathcal{H}(v)$, we obtain the existence of the absolute minimum for the Serrin forms $\mathfrak{I}(u)$ and $\mathcal{H}(v)$, and such minimum is given by BV functions, possibly discontinuous and not of Sobolev.
