Fixed Points Theorems of Ordered Contractive Maps on Noncommutative Banach spaces
Fixed point Order contractive map Noncommutative Banach space
2011/10/26
The paper introduces the concept of noncommutative Banach spaces and obtains several fixed point theorems for continuous or discontinuous ordered contractive maps in ordered noncommutative Banach spac...
Common fixed points theorem for two multivalued mappings in cone metric spaces
functional analysis common fixed point non normal cone multivalued mapping cone metric spaces
2011/10/20
In this paper, a new generalized contractive condition is introduced in metric space. By the condition and without the normality of the cone, the existence of common fixed points of multivalued mappin...
Conditions of fixed sign for $n\times n$ operator matrices
Operator matrix Hilbert space positive definiteness criterion
2010/11/26
A positive definiteness criterion and, under the additional conditions, a non-negativity criterion for a self-adjoint continuous operator matrix, acting in product of an arbitrary number of real separ...
Minimizers of the Willmore functional under fixed conformal class
Willmore surfaces conformal parametrizatio geometric measure measure
2010/12/15
We prove the existence of a smooth minimizer of the Willmore energy in the class of conformal immersions of a given closed Riemann surface into Rn, n = 3, 4, if there is one conformal immersion with W...
Continuous Selection, Collectively Fixed Points and System of Coincidence Theorems in Product Topological Spaces
continuous selection collectively fixed point $FC$-space
2007/12/11
Some new continuous selection theorems are first proved in noncompact topological spaces. As applications, some new collectively fixed point theorems and coincidence theorems for two families of set-...
A Unified Fixed Point Theory in Generalized Convex Spaces

2007/12/10
Let $\frak B$ be the class of `better' admissible multimaps due to the author. We introduce new concepts of admissibility (in the sense of Klee) and of Klee approximability for subsets of $G$-convex u...
