On a class of polynomials connected to Bell polynomials
In this paper, we study a class of sequences of polynomials linked to the
sequence of Bell polynomials. Some sequences of this class have applications on
the theory of hyperbolic differential equations and other sequences generalize
Laguerre polynomials and associated Lah polynomials. We discuss, for these
polynomials, their explicit expressions, relations to the successive
derivatives of a given function, real zeros and recurrence relations. Some
known results are significantly simplified.Comment: 13 page
The Tax Subsidy to Employment-Based Health Insurance and the Distribution of Well-Being
Pauly considers some recent contrasting views on the distributional effects of the tax subsidy within employment groups. He shows that the correct answer depends on what one assumes to be the within-group incidence of the reduction in money wages that occurs when group insurance is part of a competitive compensation package
On minimal norms on
In this note, we show that for each minimal norm on the algebra
of all complex matrices, there exist norms and
on such that for all . This may be regarded as an
extension of a known result on characterization of minimal algebra norms.Comment: 4 pages, to appear in Abstract and Applied Analysi
