Abstract


Analisis Fungsional merupakan salah satu cabang dari ilmu Matematika yang membahas tentang ruang vektor serta pemetaan di antara ruang - ruang tersebut. Pada artikel ini membahas tentang semigrup pada ruang Hilbert yang dapat dibalik dan mempunyai balikan. Untuk Semigrup yang sangat kontinu pada Ruang Hilbert, disini disajikan bukti singkat dari fakta-fakta bahwa inverse kiri dari semigrup yang dapat dibalik dan dapat dipilih menjadi semigrup juga. Lebih jauh pada tulisan ini akan ditunjukkan pula bahwa semigrup ini tidak perlu unik.

Abstract

Functional Analysis is one branch of Mathematics that deals with vector spaces and mapping between these spaces This article to discuss about semigroups on Hilbert Space. For strongly continous semigroups on Hilbert space, we present a short proof of the fact that the left inverse of a left invertible semigroup can be chosen to be a semigroups as well. Furthermore, we show that this semigroups need not to be unique.Keywords: three-five word(s) or phrase(s), that it’s  representative for the article.

Keywords
