Nonlocal Matrix Generalizations of N=2 Super Virasoro Algebra

We study the generalization of second Gelfand-Dickey bracket to the superdifferential operators with matrix-valued coefficients. The associated Miura transformation is derived. Using this bracket we work out a nonlocal and nonlinear N=2 superalgebra which contains the N=2 super Virasoro algebra as a subalgebra. The bosonic limit of this algebra is considered. We show that when the spin-1 fields in this bosonic algebra are set to zero the resulting Dirac bracket gives precisely the recently derived $V_{2,2}$ algebra.Comment: 14 pages (Plain TeX), NHCU-HEP-94-2

Interrelationships between consumers’ attitudes, behaviour toward organic food and dietary habits

This study examined the relationship between Taiwanese consumers’ attitudes and purchase behaviour toward organic food. A preliminary effort was made to identify the influence of consumers’ socio-demographic backgrounds on the variations in their responses. The dietary habits of organic product consumers are another aspect of this study

A note on the Almost Schur lemma on smooth metric measure spaces

In this paper, we prove almost Schur Lemma on closed smooth metric measure spaces, which implies the results of X. Cheng and De Lellis-Topping whenever the weighted function f is constant.Comment: 15 page
