Neutral surfaces in neutral four-spaces

open access: yesLe Matematiche, 1990
Properties of the Gauss map of neutral surfaces are studied. Special attention is given to surfaces of parallel, or zero, mean curvature. Bilagrangian structures are defined and used in ways analogous to the use of complex structures in the Riemannian ...

A Multidimensional Gauss Map

open access: yes, 2017
The classical Gauss Map is a piecewise continuous map from the unit interval to itself. From this map we retrieve the continued fraction expansion of irrational numbers and its dynamical properties give information about some arithmetic and algebraic properties of irrational numbers.

Copper(II), a Peculiar Metal Ion for Complexation with Monensin A Ionophore

open access: yesChemistry – A European Journal, EarlyView.
Copper(II) forms three chiral and EPR‐active complexes with monensinate A in methanol. Beside the bis [CuL2] and mono [CuL]+ species, the new dinuclear construct [Cu2L]3+ exhibits an [ML]+‐type and a metal salt‐type copper(II) centers weakly bound to each other through counter ion(s) and thus, being magnetically independent.

On the Gauss map of quadric surfaces

open access: yes, 2019
In this paper, we study quadric surfaces in the 3-dimensional Euclidean space whose Gauss map n is of coordinate finite I-type, i.e., the position vector n satisfies the relation {\Delta}In = {\Lambda}n, where {\Delta}I is the Laplace operator with ...

Gauss map of minimal surfaces with ramification [PDF]

open access: yesTransactions of the American Mathematical Society, 1993
We prove that for any complete minimal surface M M immersed in R n {R^n} , if in C P n − 1 C{P^{n - 1}} there are q > n

WSPLK: A systematic approach to the thermodynamic characterization of light and heavy Mexican crude oil

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract A streamlined characterization framework (WSPLK) is presented for modelling complex reservoir fluids using cubic equations of state. The key methodological contribution is the introduction of a single global parameter ε directly into Pedersen's boiling‐point correlation, restoring pure‐component calibration and eliminating the need for ...

A Non-Zonal and Non-Singular Formulation of the Gauss-Krüger Projection for Polar Regions

open access: yesMathematics
The complex analytic continuation can be developed to enable the Gauss-Krüger projection to be non-zonal and non-singular in polar regions. The series expansion of the traditional Gauss-Krüger projection in terms of third flattening has been derived by ...

Gravitational waves carrying orbital angular momentum

open access: yesNew Journal of Physics, 2016
Spinorial formalism is used to map every electromagnetic wave into the gravitational wave (within the linearized gravity). In this way we can obtain the gravitational counterparts of Bessel, Laguerre-Gauss, and other light beams carrying orbital angular ...

Playing with fire? A mean‐field game analysis of fire sales and systemic risk under regulatory capital constraints

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract We analyze the effect of regulatory capital constraints on financial stability in a large homogeneous banking system using a mean‐field game (MFG) model. Each bank holds cash and a tradable risky asset. Banks choose absolutely continuous trading rates in order to maximize expected terminal equity, with trades subject to transaction costs ...
