We define higher polyhedral K-groups for commutative rings, starting from the stable groups of elementary automorphisms of polyhedral algebras. Both Volodin’s theory and Quillen’s + construction are developed. In the special case of algebras associated with unit simplices one recovers the usual algebraic K-groups, while the general case of lattice polytopes reveals many new aspects, governed by...
متن کاملWinfried Bruns And
We describe some of the determinantal ideals attached to symmetric, exterior and tensor powers of a matrix. The methods employed use elements of Zariski’s theory of complete ideals and of representation theory. Let R be a commutative ring. The determinantal ideals attached to matrices with entries in R play ubiquitous roles in the study of the syzygies of R–modules. In this note, we describe so...
متن کامل2 Winfried Bruns And
We overview results from our experiment of merging two seemingly unrelated disciplines – higher algebraic K-theory of rings and the theory of lattice polytopes. The usual K-theory is the “theory of a unit simplex”. The text is based on the works [BrG1, BrG5, BrG6]. Further related results are found in [BrG2, BrG3, BrG4]. At the end of the paper we propose a general conjecture on the structure o...
متن کاملViktor Hamburger (1900-2001)
Viktor Hamburger [5] was an embryologist who focused on neural development [6]. His scientific career stretched from the early 1920s as a student of Hans Spemann [7] to the late 1980s at Washington University [8] resolving the role of nerve growth factor [9] in the life of neurons. Hamburger is noted for his systematic approach to science and a strict attention to detail. Throughout his life he...
متن کاملBruns Syndrome: a deadly sign
Bruns syndrome was first described in 1902, as a sudden onset of severe headaches and vomiting associated to a vestibular syndrome provoked by abrupt change in head position. It is related to an episodic obstructive hydrocephalous caused by an intraventricular mass that acts like a ball-valve mechanism. A 52 years old man was admitted to the intensive care unit for a sudden onset coma. His Glas...
