Rotational Invariance of Quadromer Correlations on the Hexagonal Lattice
نویسنده
چکیده
In 1963 Fisher and Stephenson [FS] conjectured that the monomer-monomer correlation on the square lattice is rotationally invariant. In this paper we prove a closely related statement on the hexagonal lattice. Namely, we consider correlations of two quadromers (four-vertex subgraphs consisting of a monomer and its three neighbors) and show that they are rotationally invariant.

Biotite is a common rock-forming mineral and accepts a variety of elements in its structure. The valuable information of crystallization conditions of the biotite mineral obtain on natural biotite composition. The biotite mineral is one of the main mineral phases of pelitic rocks which are formed in a wide range of geological conditions. In this research, microscopic mineralogy, Raman spectrosc...
متن کاملInfluence of optical Kerr coefficient on photonic band structures of hexagonal-lattice function photonic crystals
In this paper, we have studied the photonic band structure of function photonic crystals in which the dielectric constant of the scattering centers (rods) is a function of space coordinates. The under-studied lattice is hexagonal and cross section of rods has a circular symmetry embedded in the air background. Photonic band structures for both electric and magnetic polarizations of the electrom...

In this paper, a new structure is provided for the dispersion compensating photonic crystal fibers in order to broaden the chromatic dispersion and increase the dispersion compensating capability in a wide wavelength range. In the structure, putting elliptical holes in the first ring of the inner core clad of a dispersion compensating fiber of the hexagonal lattice, increases the wavelength ran...
متن کاملHexaConv
The effectiveness of convolutional neural networks stems in large part from their ability to exploit the translation invariance that is inherent in many learning problems. Recently, it was shown that CNNs can exploit other sources of invariance, such as rotation invariance, by using group convolutions instead of planar convolutions. However, for reasons of performance and ease of implementation...
متن کاملScale-invariant memory representations emerge from moiré interference between grid fields that produce theta oscillations: a computational model.
The dorsomedial entorhinal cortex (dMEC) of the rat brain contains a remarkable population of spatially tuned neurons called grid cells (Hafting et al., 2005). Each grid cell fires selectively at multiple spatial locations, which are geometrically arranged to form a hexagonal lattice that tiles the surface of the rat's environment. Here, we show that grid fields can combine with one another to ...
