purpose: to determine stereopsis with local (titmus) and global (tno) tests in symptomatic and asymptomatic subjects according to induced disparity (crossed or uncrossed). methods: in this cross sectional study, 80 students of zahedan university of medical sciences who fulfilled the inclusion criteria were randomly selected. at first, refractive error was determined by retinoscopy and then base...
in this work we deal with actions of vector groupoid which is a new concept in the literature. after we give the definition of the action of a vector groupoid on a vector space, we obtain some results related to actions of vector groupoids. we also apply some characterizations of the category and groupoid theory to vector groupoids. as the second part of the work, we define the notion...
The Hochschild and (cotriple) cyclic homologies of crossed modules of (notnecessarily-unital) associative algebras are investigated. Wodzicki’s excision theorem is extended for inclusion crossed modules in the category of crossed modules of algebras. The cyclic and cotriple cyclic homologies of crossed modules are compared in terms of long exact homology sequence, generalising the relative cycl...
Results on the finiteness of induced crossed modules are proved both algebraically and topologically. Using the Van Kampen type theorem for the fundamental crossed module, applications are given to the 2-types of mapping cones of classifying spaces of groups. Calculations of the cohomology classes of some finite crossed modules are given, using crossed complex methods.
