This paper presents a new generating function for Hermite polynomials of one variable in the form of $g(x,t)=\sum_{n=0}^{\infty }t^{n}H^{e}_{n}(x)$ and reveals its connection with incomplete gamma function.
The present paper introduces a method of basis transformation of a vector space that is specifically applicable to polynomials space and differential equations with certain polynomials solutions such as Hermite, Laguerre and Legendre polynomials. This method is based on separated transformations of vector space basis by a set of operators that their overall action is equivalent to the formal basis transformation and connected to it by linear combination with projection operators. By introducing the new relations for projection operators under separated transformation and applying the Forbenius covariants as projection operators, we derive a general method that incorporates the Rodrigues formula as a special case in polynomial space. A solution method to some classical differential equation such as Hermite and Laguerre differential equations is presented.
This paper presents the connections between univariate and bivariate Hermite polynomials and associated differential equations with specific representations of Lie algebra sl(2,R) whose Cartan sub-algebras coincide the associated differential operators of these differential equations . Applying the Baker-Campbell-Hausdorff formula to generators of these algebras, results in new relation for one-variable and Bivariate Hermite polynomials. A general form of sl(2,R) representation by differential operators and arbitrary polynomial basis such as Laguerre and Legendre polynomials is introduced.
We introduce a type of symmetry breaking and associated order parameter in connection with Laplace-Runge-Lenz vector of Kepler orbit through an extended spatial dimension and Ensemble view. By implementation of a small extra spatial dimension and embedded infinitesimal toral manifold, it has been shown that emerging of LRL vector under SO(4)symmetry is in analogy with a variety of explicit and spontaneous symmetry breaking situations and related Goldstone bosons such as phonons and spin waves. A theorem introduced to generalize this concept of breaking symmetry. The diffeomorphism of circular orbit(geodesic)to elliptic one proved to be equivalent with a covariant derivative and related parallel displacement in this extended four dimensional spatial space.Respect to ensemble definition this diffeomorphism breaks the O(2) symmetry of initial orbit and Hamiltonian to Z2 resulting in broken generators in quotient space and associated Goldstone boson as perturbing Hamiltonian term leading to a perpetual circular motion on 2-torus comparable to the perpetual motion idea in Time Crystal of Wilczek. This leads to an introduction of gravitational gauge potential under the symmetry of Cartan sub algebra of su(2).
