15 صفحه اولThe Matrix Sign Decomposition and Its Relation to the Polar Decomposition
The sign function of a square matrix was introduced by Roberts in 1971. We show that it is useful to regard S = sign(A) as being part of a matrix sign decomposition A = SN, where N = (A ) ’ 1/z This decomposition leads to . the new representation sign(A) = A(A2)-‘i2. Most results for the matrix sign decomposition have a counterpart for the polar decomposition A = UH, and vice versa. To illustra...
متن کاملlexical decomposition awareness and its effect on delayed receptive and productive recognition and recall of vocabulary knowledge of morphologically complex english words: an iranian efl context
abstract lexical knowledge of complex english words is an important part of language skills and crucial for fluent language use (nation, 2001). the present study, thus, was an attempt to assess the role of morphological decomposition awareness as a vocabulary learning strategy on learners’ productive and receptive recall and recognition of complex english words. so 90 sophomores (female and ma...

In this paper we consider the polar decomposition on a Lie group G endowed with an involutive automorphism , as considered in (Munthe-Kaas, Quispel & Zanna 2000). In that paper, among other things, it was shown that z = exp(tZ) 2 G, Z 2 g, can be decomposed as z = xy, where x = exp(X(t)) and y = exp(Y (t)), where X(t) 2 p and Y (t) 2 k, g = p k being a Cartan decomposition of the algebra g indu...
