Nonparametric IV estimation of shape-invariant Engel curves [PDF]
This paper concerns the identification and estimation of a shape-invariant Engel curve system with endogenous total expenditure. The shape-invariant specification involves a common shift parameter for each demographic group in a pooled system of Engel ...

n-quasi-isotopy: III. Engel conditions
, 2002 In part I it was shown that for each k>0 the generalized Sato-Levine invariant detects a gap between k-quasi-isotopy of link and peripheral structure preserving isomorphism of the finest quotient G_k of its fundamental group, `functorially' invariant under k-quasi-isotopy.

Testing for Shape Invariance of Semiparametric Equivalence Scales [PDF]
Within a semiparametric framework we propose a test of shape invariance of Engel curves, which is a necessary condition for base independence. Using Canadian family expenditure data for 1996 we reject shape invariance for the fuel and clothing share ...

Group Rings Satisfying Generalized Engel Conditions
Mathematical Researches, 2020 Let R be a commutative ring with unity of characteristic r≥0 and G be a locally finite group. For each x and y in the group ring RG define [x,y]=xy-yx and inductively via [x ,_( n+1) y]=[[x ,_( n) y] , y]. In this paper we show that necessary and sufficient conditions for RG to satisfies [x^m(x,y) ,_( n(x,y)) y]=0 is: 1) if r is a power of a ...

The Engel elements in generalized FC-groups
, 2014 We generalize to FC*, the class of generalized FC-groups introduced in [F. de Giovanni, A. Russo, G. Vincenzi, Groups with restricted conjugacy classes, Serdica Math. J. 28 (2002), 241-254], a result of Baer on Engel elements.

Lie rings and the Engel condition
Journal of Algebra, 1974 In his work dealing with the restricted Burnside problem, Kostrikin showed that a Lie ring of prime characteristic \(p\) satisfying an \(n\)-th Engel condition, where \(n\leq p\), is locally nilpotent. Theorem 1 in the paper under review is an extension of this result to the case \(n= p+ 1, p\geq 3\).

Stable pair compactification of moduli of K3 surfaces of degree 2
, 2019 We prove that the universal family of polarized K3 surfaces of degree 2 can be extended to a flat family of stable slc pairs $(X,\epsilon R)$ over the toroidal compactification associated to the Coxeter fan.
