The aim of this work is to prove a chain rule and an $L^1$-lower semicontinuity theorems for integral functional defined on $BV(\Omega)$. Moreover we apply this result in order to obtain new relaxation and $\Gamma$-convergence result without any coerciveness and any continuity assumption of the integrand $f(x,s,p)$ with respect to the variable $s$.
Keywords: relaxation, Lower Semicontinuity, BV functions, Chain Rule
