Groupoids and the Associative Law Xii. (representable Cardinal Functions)
In this paper we investigate under what conditions is a mapping f of a semigroup S into the class of cardinals representable by a groupoid G and a homomorphism g of G onto S such that ker(g) is the associativity congruence of G and Card(g(x)) = f(x) for every x ∈ S. Abstrakt. V tomto článku vyšetřujeme, za jakých podmı́nek lze zobrazeńı f pologrupy S do tř́ıdy všech kardinálńıch č́ısel reprezentov...
متن کاملOn Spectra of Geometric Operators on Open Manifolds and Differentiable Groupoids
We use a pseudodifferential calculus on differentiable groupoids to obtain new analytical results on geometric operators on certain noncompact Riemannian manifolds. The first step is to establish that the geometric operators belong to a pseudodifferential calculus on an associated differentiable groupoid. This then leads to Fredholmness criteria for geometric operators on suitable noncompact ma...
متن کاملPower-associative, Conjugacy Closed Loops
We study conjugacy closed loops (CC-loops) and power-associative CC-loops (PACC-loops). If Q is a PACC-loop with nucleus N , then Q/N is an abelian group of exponent 12; if in addition Q is finite, then |Q| is divisible by 16 or by 27. There are eight nonassociative PACC-loops of order 16, three of which are not extra loops. There are eight nonassociative PACC-loops of order 27, four of which h...
متن کاملn-groupoids and stacky groupoids
We discuss two generalizations of Lie groupoids. One consists of Lie n-groupoids defined as simplicial manifolds with trivial πk≥n+1. The other consists of stacky Lie groupoids G ⇒ M with G a differentiable stack. We build a 1–1 correspondence between Lie 2-groupoids and stacky Lie groupoids up to a certain Morita equivalence. We prove this in a general set-up so that the statement is valid in ...
متن کاملOn the Computational Power of Timed Differentiable Petri Nets
Two kinds of well studied dynamical systems are state and time discrete ones (important in Computer Science) and state and time continuous ones (heavily considered in Automatic Control). Whereas in the discrete setting, the analysis of computational power of models has led to well-known hierarchies, the situation is more confused in the continuous case. A possible way to discriminate between th...
