This paper explores the understanding of architectural spaces driven by knowledge that animals communicate modifying environment, in which they live. The way environment forms an interaction, is referred to as stigmergy, a mediated form animal interaction. elaborates on process colonies with their living and leave different kinds spatial traces. argues stigmergy can be potentially used basis pr...

In this article, normal paracontact metric space forms are investigated on W_0-curvature tensor. Characterizations of obtained Special curvature conditions established with the help Riemann, Ricci, concircular tensors discussed With these conditions, important characterizations obtained.

A choice correspondence is weak justified if a non-chosen alternative is dominated by any other obtainable alternative, and for each discarded alternative there is some chosen alternative which dominates it. This definition allows us to build a connection between the behavioral property expressed by the weak axiom of revealed non-inferiority and a weak form of maximality. It is weaker than the ...

In this work gravitational collapse of a spherical cloud, consists of both dark matter and dark energy in the form of modified Chaplygin gas is studied. It is found that dark energy alone in the form of modified Chaplygin gas forms black hole. Also when both components of the fluid are present then the collapse favors the formation of black hole in cases the dark energy dominates over dark matt...
