Topological frame extension [PDF]
The concept of nearness on a set was introduced by H. Herrlich. D. Le- seberg generalized nearness by introducing supernearness, which generalizes also supertopology as de ned by D. Doitchinov.

Extension of Lorenz Unpredictability [PDF]
It is found that Lorenz systems can be unidirectionally coupled such that the chaos expands from the drive system. This is true if the response system is not chaotic, but admits a global attractor, an equilibrium or a cycle.

On Extension Of Functors [PDF]
A.Chigogidze defined for each normal functor on the category Comp an extension which is a normal functor on the category Tych. We consider this extension for any functor on the category Comp and investigate which properties it preserves from the ...

Extension Groups for DG Modules [PDF]
Let $M$ and $N$ be differential graded (DG) modules over a positively graded commutative DG algebra $A$. We show that the Ext-groups $\operatorname{Ext}^i_A(M,N)$ defined in terms of semi-projective resolutions are not in general isomorphic to the Yoneda

This study explores how smallholder coffee farmers’ perceptions may influence their engagement in peer mobilization and collective action. Forty smallholder coffee farmers were interviewed in the Central Highlands region of Peru using a closed-ended ...

We develop a natural five term exact sequence relating the second and third cohomology of groups. We show that this sequence is the proper framework for the problem of realizing an abstract kernel. As an application, we give an interpretation of the third cohomology of a group in terms of crossed sequences.

Aspects of the Stueckelberg Extension [PDF]
A detailed analysis of a Stueckelberg extension of the electro-weak gauge group with an extra U(1) factor is presented for the Standard Model as well as for the MSSM.

Multipoint normal differential operators of first order [PDF]
In this paper we discuss all normal extensions of a minimal operator generated by a linear multipoint differential-operator expression of first order in the Hilbert space of vector-functions on the finite interval in terms of boundary and interior point ...

Summary In this article we continue the formalization of field theory in Mizar. We introduce simple extensions: an extension E of F is simple if E is generated over F by a single element of E, that is E = F (a) for some a ∈ E. First, we prove that a finite extension E of F is simple if and only if there are only finitely many ...

Recent changes in rice production in rainfed lowland and irrigated ecosystems in Thailand
While Thailand is a major rice exporting country in the world, the yield is low among Asian countries. In order to identify factors determining the changes in rice productivity in the country for the last 45 years (1974–2018), various data on production ...
