Ehresmann's theorem
WebIn this paper, inspired by the approach of Jones [‘A common framework for restriction semigroups and regular $\ast$-semigroups’, J. Pure Appl. Algebra 216 (2012), 618–632], Ehresmann semigroups are extended from a varietal perspective to pseudo-Ehresmann semigroups derived instead from reducts of regular semigroups with a multiplicative ...

WebThe Riemann curvature tensor is also the commutator of the covariant derivative of an arbitrary covector with itself:;; =. This formula is often called the Ricci identity. This is the classical method used by Ricci and Levi-Civita to obtain an expression for the Riemann curvature tensor. This identity can be generalized to get the commutators for two … WebAug 1, 2024 · Theorem 2.7 Stein [86, Theorem 1.5] Let S be an E-Ehresmann semigroup that is either left- or right-restriction, and suppose ≤ r or ≤ l (as appropriate) is finite …
