Uniform Approximation by Elementary Operators

On a separable C-algebra A every (completely) bounded map which preserves closed two sided ideals can be approximated uniformly by elementary operators if and only if A is a finite direct sum of C-algebras of continuous sections vanishing at ∞ of locally trivial C-bundles of finite type.

Elementary arithmetic

There is a quite natural way in which the safe/normal variable discipline of Bellantoni-Cook recursion (1992) can be imposed on arithmetical theories like PA: quantify over safes and induct on normals. This weakens the theory severely, so that the provably recursive functions become more realistically computable (slow growing rather than fast growing). Earlier results of Leivant (1995) are re-w...

Elementary Hygiene

This small book has been written to meet the requirements of matriculation students in the Punjab and other parts of India, where the subject of elementary hygiene is studied along with a course of physiology. From a perusal of the book, we can say that the authors have carried out their object well. Facts are clearly stated and in the recommendations and advice given, full cognisance of Indian...
