with a finite number of exceptions for the values of re. But it has not yet been made clear what values of re are exceptional. This note will give an answer to the analogous problem for a wider interval of the dimension of G. In §1 we shall explain some notations and then, in §2, a relation between irreducibility and absolute irreducibility will be discussed; especially a condition for a representation to be unitary symplectic will be given. In §3 we shall obtain inequalities concerning the… Expand
Homogenisation On Homogeneous Spaces
Motivated by collapsing of Riemannian manifolds and inhomogeneous scaling of left invariant Riemannian metrics on a real Lie group G with a sub-group H , we consider a family of stochasticExpand
Topological and geometric obstructions on Einstein–Hilbert–Palatini theories
Abstract In this article we introduce A -valued Einstein–Hilbert–Palatini functional ( A -EHP) over a n -manifold M , where A is an arbitrary graded algebra, as a generalization of the functionalExpand
Rolling of Manifolds and Controllability in Dimension Three
In this paper, we present the rolling (or development) of one smooth connected complete Riemannian manifold (M, g) onto another one (M̂, ĝ) of equal dimension n ≥ 2 where there is no relative spin orExpand
Geometric Obstructions on Gravity
These are notes for a short course and some talks gave at Departament of Mathematics and at Departament of Physics of Federal University of Minas Gerais, based on the author's paper arXiv:1808.09249.Expand
Rolling Manifolds: Intrinsic Formulation and Controllability
In this paper, we consider two cases of rolling of one smooth connected complete Riemannian manifold $(M,g)$ onto another one $(\hM,\hg)$ of equal dimension $n\geq 2$. The rolling problem $(NS)$Expand
Symmetry principles in quantum system theory of multi-qubit systems made simple
Controllability and observability of multi-spin systems in architectures of various symmetries of coupling type and topology are investigated. We complement recent work of explicitly determining theExpand
Symmetry principles in quantum systems theory
General dynamic properties such as controllability and simulability of spin systems, fermionic and bosonic systems are investigated in terms of symmetry. Symmetries may be due to the interactionExpand
Stochastic Homogenization on Homogeneous Spaces October
Motivated by inhomogeneous scaling of left invariant Riemannian metrics on a Lie group G, we consider a family of stochastic differential equations (SDEs) on G with Markov operators L = 1 ∑ k(Ak) 2 +Expand
Stochastic Homogenisation on Homogeneous Spaces
Let G be a Lie group with a closed subgroup H and a left invariant Riemannian metric. We study a family of stochastic differential eq uations arising from inhomogeneous scaling of the RiemannianExpand
A dynamic systems approach to fermions and their relation to spins
The key dynamic properties of fermionic systems, like controllability, reachability, and simulability, are investigated in a general Lie-theoretical frame for quantum systems theory. It just requiresExpand


A class of affinely connected spaces
It is known that the existence of a group G of motions of sufficiently high dimension in an w-dimensional Riemannian space imposes strong restrictions on the space [10; 15; 16]. This restriction isExpand
Transformation Groups of Spheres
1. The compact Lie group G is said to be a transformation group of the space TW or to act on the space W if the following conditions are satisfied: a) to every element g of G there is associated aExpand
