  • The purpose of this study is to analyze the multi-layered space utilized as strategy for deconstruction in the architecture of Hiromi Fujii. Although the design of Eisenman and Fujii was based on the philosophical theory of Jacques Derrida, there are many different aspects of architecture. At the same time, Hiromi Fujii could construct his concept of multi-layered space to colligate the academic knowledge of Jacques Derrida, Roman Jakobson and Colin Rowe. This kind of concept for multi-layered space is a critical element to be distinct from the characters between two architects, and it is implied such as an significant concept to analyze the architecture for Hiromi Fujii. This multi-layered space contains interesting and researchable value to understand and to analyze the western architecture theory from the viewpoint of Asian architect. Accordingly, the purpose of the thesis is to find the meaning to establish an theoretical foundation for being under discussion to the architecture of Fujii through the concept of multi-layered space.

  • We show that for an algebraic Riccati equation $X^*B^{-1}X-T^*X-X^*T=C$, its solutions are given by X = W + BT for some solution W of $X^*B^{-1}X$ = $C+T^*BT$. To generalize this, we give an equivalent condition for $\(\array{B&W\\W*&A}\)\;{\geq}\;0$ for given positive operators B and A, by which it can be regarded as Riccati inequality $X^*B^{-1}X{\leq}A$. As an application, the harmonic mean B ! C is explicitly written even if B and C are noninvertible.
