This paper deals with real operator spaces. By definition, a real operator space is a (closed) subspace of \(B(H)\), the space of all bounded linear operators on a real Hilbert space. The author gives an abstract characterization of such spaces, similar to his famous theorem on the characterization of the usual (complex) operator spaces.

Imbeddings of Real Projective Spaces
The Annals of Mathematics, 1962THEOREM II. Suppose n = 4k + 1, but k is not a power of 2. Then Pa can be imbedded in (2n 2)-space. In each case the result would be false for k a power of 2. Pa cannot be imbedded in (2n 1)-space for n = 2r, by a result of Stiefel or Thom, [11, p. 157, III. 16].

Pointing in Real Euclidean Space
Journal of Guidance, Control, and Dynamics, 1997We treat the following problem. Given two vectors of the same length, find an orthogonal transformation that transforms one to the other. This problem arises in many different engineering fields. In particular, it arises in aerospace engineering, where it is called the pointing problem. We establish the theoretical background of the pointing problem in

Up to now, I have been concerned with the ways in which Lacan, from the 1940s to the beginning of the 1960s, laid the ground for a psychoanalysis predicated on the Real. By showing the place of the Real in the Imaginary and Symbolic, I hope to have begun to show how the concerns of the ‘later Lacan’, who it is sometimes assumed would come to focus on ...

With regard to social lifestyles of human beings, we should always have some inhibiting frameworks in order to prevent occurrence of damage to each other. Cyber space has become a virtual place in which real human beings are now interacting just as they interact in real spaces in the world.

Field operators are widely used in many-body theory of indistinguishable particles. In this work it is shown that these operators can be represented solely in position space. Explicit expressions for the field operators in position space are given. Using the derived expression, we further show how by generalizing operators in first quantization to ...

An application of an agent space connecting real space and digital space
2014 IEEE 13th International Conference on Cognitive Informatics and Cognitive Computing, 2014Using the ICT and the ubiquitous technology, very convenient services have been provided for users daily and widely. However, users feel a heavy burden on finding information they need at each situation rapidly, because the important information may hide in enormous useless information in the Internet.

THE REAL COHOMOLOGY OF HOMOGENEOUS SPACES
Russian Mathematical Surveys, 1969The main object of this article is to give an account of the results of H. Cartan on the real cohomology algebra of a homogeneous space associated with a compact group. The exposition is based on the theory of Lie algebras and algebras connected with them and contains a number of incidental constructions and results of an algebraic character.
