演化$Γ$ -弱型收敛

Evolutionary $Γ$-convergence of weak-type

Augusto Visintin

摘要:

对作用于含时函数的算子序列引入了演化$Γ$ -弱型收敛的概念。这扩展了经典定义的$Γ$ -收敛的泛函由于德Giorgi。证明了等强制等有界算子列的$Γ$ -紧性。应用包括伪单调算子的拟线性流的结构紧性和稳定性。

英文摘要:

A notion of evolutionary $Γ$-convergence of weak type is introduced for sequences of operators acting on time-dependent functions. This extends the classical definition of $Γ$-convergence of functionals due to De Giorgi. The $Γ$-compactness of equi-coercive and equi-bounded sequences of operators is proved. Applications include the structural compactness and stability of quasilinear flows for pseudo-monotone operators.
