Joint Differential Invariants of Binary and Ternary Forms

چکیده
We construct and classify the joint invariants and joint differential invariants of binary and ternary forms. In particular, we prove that the differential invariant algebra of ternary forms is generated by a single third order differential invariant. To connect our results with earlier analysis of Kogan, we develop a general method for relating differential invariants associated with different choices of cross-section.

The MAPLE package for calculating Poincaré series
Abstract. We offer a Maple package Poincare_Series for calculating the Poincaré series for the algebras of invariants/covariants of binary forms, for the algebras of joint invariants/covariants of several binary forms, for the kernel of Weitzenböck derivations,for the bivariate Poincaré series of algebra of covariants of binary d-form and for the multivariate Poincaré series of the algebras of ...
متن کاملThermodynamic analysis of nanocrystalline solid solution formation in the W-Co-Si ternary system by mechanical alloying
Co3W2Si intermetallic compound was synthesized by mechanical alloying (MA) of W, Co and Si elemental powder mixtures. The phase composition of the milled products was evaluated by X-ray diffraction (XRD) analysis. Morphological evolutions were characterized by transmission electron microscopy (TEM). The results showed that high energy ball milling performed in the present work led to the format...
متن کاملAssociated Forms in Classical Invariant Theory and Their Applications to Hypersurface Singularities
It was conjectured in the recent article [EI] that all absolute classical invariants of forms of degree m ≥ 3 on C can be extracted, in a canonical way, from those of forms of degree n(m−2) by means of assigning every form with non-vanishing discriminant the so-called associated form. This surprising conjecture was confirmed in [EI] for binary forms of degree m ≤ 6 and ternary cubics. In the pr...
متن کاملSemi Empirical Calculation of Intermolecular Potentials and Transport Properties of Some Binary and Ternary Industrial Refrigerant Mixtures
In this study the intermolecular potential energies of some environment-friendly industrial HFC refrigerants were obtained through the inversion method which is based on the corresponding states principle. These potentials were later employed in calculation of transport properties (viscosity, diffusion, thermal conductivity and thermal diffusion factor) of some binary and ternary refrigerant mi...
متن کاملMeasurement of Thermophysical Properties of Pure and Mixture of Alkanolamines from 288.15-323.15 K
Density, viscosity and refractive index of pure, binary and ternary mixtures of diethanolamine (DEA) and methyl diethanolamine (MDEA) with water have been measured at different temperatures from 288.15 K to 323.15 K at atmospheric pressure. Also, this study presents the effects of mixture composition and temperature upon these thermo- physical properties. To measure the density and refractive i...
