A note on L. Zhou's result on Finsler surfaces with K = 0 and J = 0

Finsler Metrics with K = 0 and S = 0

In Finsler geometry, there are infinitely many models of constant curvature. The Funk metrics, the Hilbert-Klein metrics and the Bryant metrics are projectively flat with non-zero constant curvature. A recent example constructed by the author is projectively flat with zero curvature. In this paper, we introduce a technique to construct non-projectively flat Finsler metrics with zero curvature i...

Studies of Three-Body B^+→D ̅^* 〖(2007)〗^0 K^+ K ̅^0 and B^0→D^* 〖(2010)〗^- K^+ K ̅^0 Decays

We analyze three-body decays of and . Under the factorization approach, there are tree level diagrams for these decay modes and the transition matrix element of decay is factorized into a form factor multiplied by decay constant and form factor multiplied into weak vertices form factor. The transition matrix element of decay is also factorized into a form factor multiplied into weak vertic...

Sections on Certain J = 0 Elliptic Surfaces

It is well known that elliptic curves E over a function field k(t) are in 1-1 correspondence with elliptic surfaces E → P1 over k. The geometric interpretation of points in E(k(t)) arising in this way has led to a lot of results; see, e.g., [Sh72], [Sh90]. For instance, if char(k) = 0 and E is not isomorphic over k(t) to a curve already defined over k, then rank E(k(t)) ≤ 10pg+8, where pg is th...

A Note on Finsler Modules

On strongly J-clean rings associated with polynomial identity g(x) = 0

In this paper, we introduce the new notion of strongly J-clean rings associated with polynomial identity g(x) = 0, as a generalization of strongly J-clean rings. We denote strongly J-clean rings associated with polynomial identity g(x) = 0 by strongly g(x)-J-clean rings. Next, we investigate some properties of strongly g(x)-J-clean.
