## Abstract Bjorkenβlike sum rules have proven to be very powerful in constraining the derivatives of the IsgurβWise (IW) function. We expose here, adapted to the simpler case of the baryon transition Ξ~b~ β Ξ~c~ β Ξ½ (j = 0 for the light could), that the reason behind these strong constraints is th
This paper is motivated by the behavior of the heat diffusion kernel p t (x) on a general unimodular Lie group. Indeed, contrary to what happens in R n , the P t (x) on a general Lie group is behaving like t &$(t)Γ2 for two possibly distinct integers $(t), one for t tending to 0 and another for t te
## Abstract We study trilinear and multilinear invariant forms for the homogeneous Lorentz group. The residues of these trilinear forms generate particular trilinear forms themselves. They appear also if we sum Taylor expansions partially into a series of expressions each of which is covariant unde
