Ernst denklemi

Ernst denklemi, Matematik'te Doğrusal-Olmayan bir Kısmi Türevsel Denklem'dir.

Adı

Ünlü fizikçi Frederick J. Ernst[1] tarafından bulunmuş olduğundan, "Ernst denklemi" olarak adlandırılmıştır.

Ernst denklemi

Sağ tarafında Birinci dereceden kısmî türevler içeren ve doğrusal olmayan terimleri olan bir denklemdir. Çözümü aranan u karmaşık fonksiyonunun gerçel kısmı R(u), denklemin sol tarafındaki İkinci dereceden kısmî türevlerin çarpımı halinde belirdiğinden, denklemin her iki tarafı da doğrusal-olmayan (non-linear) terimler ihtivâ etmektedir. Denklem aşağıdaki şekilde verilmektedir:[2]

Kullanım amacı

Einstein alan denklemlerinin noksansız çözümlerini elde etmek için kullanılan doğrusal olmayan bir kısmi türevsel denklemdir.
