ARBITRARY-ORDER HERMITE GENERATING FUNCTIONS FOR COHERENT AND SQUEEZED STATES
For use in calculating higher-order coherent- and squeezed- state quantities,
we derive generalized generating functions for the Hermite polynomials. They
are given by , for arbitrary
integers and . Along the way, the sums with the Hermite
polynomials replaced by unity are also obtained. We also evaluate the action of
the operators on well-behaved functions and apply them to
obtain other sums.Comment: LaTeX, 8 page
Contact systems and corank one involutive subdistributions
We give necessary and sufficient geometric conditions for a distribution (or
a Pfaffian system) to be locally equivalent to the canonical contact system on
Jn(R,Rm), the space of n-jets of maps from R into Rm. We study the geometry of
that class of systems, in particular, the existence of corank one involutive
subdistributions. We also distinguish regular points, at which the system is
equivalent to the canonical contact system, and singular points, at which we
propose a new normal form that generalizes the canonical contact system on
Jn(R,Rm) in a way analogous to that how Kumpera-Ruiz normal form generalizes
the canonical contact system on Jn(R,R), which is also called Goursat normal
form.Comment: LaTeX2e, 29 pages, submitted to Acta applicandae mathematica

Solvability of eigenvalues in jn configurations
Eigenvalues of eigenstates in jn configurations (n identical nucle- ons in
the j -orbit) are functions of two-body energies. In some cases they are linear
combinations of two-body energies whose coe+/-cients are independent of the
interaction and are rational non-negative num- bers. It is shown here that a
state which is an eigenstate of any two-body interaction has this solvability
property. This includes, in particular, any state with spin J if there are no
other states with this J in the jn configuration. It is also shown that
eigenstates with solvable eigenvalues have definite seniority v and thus,
exhibit partial dynamical symmetry

Le prologue du quatrième évangile, clé de voûte de la littérature johannique
Like its last verse (Jn 1.18), the Prologue of the Johannine Gospel has a double meaning: christological and soteriological. The christological one is mainly connected with John 1-20, the soteriological with John 21, and both are linked to 1 John. Indeed, while the Prologue interacts with the Gospel narrative and with the Epilogue (Jn 21), it works also as a ‘relecture' (re-reading) of 1 John. It recapitulates the promise by Jesus to lead the believers ‘where he is'—i.e. ‘in(to) the bosom of the Father' (Jn 1.18//Jn 12.26; 14.2-3, 6; 17.24)—as well as the assertion of the Letter regarding the children of God (Jn 1.12//1 Jn 3.1-2). In adding a Prologue and an Epilogue, the last redactor of Jn created a huge meta-historical arch evoking the whole Divine design, from the Alpha before the Creation (ἐν ἀρχῇ, Jn 1.1-2) to the Omega of the eschatological coming of the Risen One (ἕως ἔρχομαι, Jn 21.22, 23; cf. the παρουσία of 1 Jn 2.28). The Prologue is then the keystone and the reading key of the Johannine literatur
