F-signature of pairs and the asymptotic behavior of Frobenius splittings
F-signature Cartier algebra F-pure F-regular splitting prime F-splitting ratio
2011/8/26
Abstract: We generalize $F$-signature to pairs $(R,D)$ where $D$ is a Cartier subalgebra on $R$ as defined by the first two authors. In particular, we show the existence and positivity of the $F$-sign...

Tanno-Theorem Kä hlerian metrics arbitrary signature
2011/1/18
Considering a non-constant smooth solution f of the Tanno equation on a closed,connected K¨ahler manifold (M, g, J) with positively definite metric g, Tanno showed that the manifold can be finitely co...

The everlasting bandwidth limitations in wireless communication networks has directed the researchers’ thrust toward analyzing the prospect of overloaded Code Division Multiple Access (CDMA).
Partial Rigidity of CR Embeddings of Real Hypersurfaces into Hyperquadrics with Small Signature Difference
Partial Rigidity Real Hypersurfaces Signature Difference
2010/11/11
We study the rigidity of holomorphic mappings from a neighborhood of a Levi-nondegenerate CR hypersurface $M$ with signature $l$ into a hyperquadric $Q_{l'}^{N} \subseteq \mathbb{CP}^{N+1}$ of larger ...

Cryptanalysis on Chen-Qiu-Zheng blind signature scheme
Blind Signatures Security Privacy Cryptology
2010/9/10
Chen, Qiu, and Zheng proposed a Rabin-like blind signature scheme, which is based on the square-root problem. Although their scheme is simple and efficient, it can be compromised when choosing some pa...
A novel identity-based society oriented signature scheme with anonymous signers
RSA cryptosystem society signature
2010/9/15
Recently, Saeedina proposed an identity-based society oriented signature scheme with anonymous signers based on the Quillou-Quisquater signature scheme. The scheme is identity-based and the signatures...
