Almost coreflective and projective classes

Applied Categorical Structures, 1994
The paper gives a general (Freyd-Kelly type) criterion for a projectivity class in a category to be almost coreflective (= weakly coreflective and closed under coretracts). Various interesting examples and applications mostly to topological categories are also provided.

Projective Homotopy Classes of Stiefel Manifolds

Canadian Journal of Mathematics, 1972
Given a homotopy class [f] in πn(X), we say that [f] is projective if and only if there is a homotopy commutative factorizationwhere v is the standard double covering. We then denote by the subset of projective homotopy classes in πn(X).The notion of projective homotopy classes was studied in the author's thesis [5], and the projective homotopy ...

Computing characteristic classes of projective schemes [PDF]

Journal of Symbolic Computation, 2003
. We discuss an algorithm computing the push-forward to projective space of several classes associated to a (possibly singular, reducible, nonreduced) projective scheme.

A few projective classes of (non-Hausdorff) topological spaces [PDF]

Topology and Its Applications
A class of topological spaces is projective (resp., $ω$-projective) if and only if projective systems of spaces (resp., with a countable cofinal subset of indices) in the class are still in the class.

Neoliberalism, a Class Project

2015
Neoliberalism has become a relatively popular concept in critical scholarship, having been used in a variety of contexts while taking on a range of meanings (Boas and Gans-Morse, 2009; for surveys, see Saad-Filho and Johnston, 2005b; Roy et al., 2006; Steger and Roy, 2010).

Concurrent Projects in Control Laboratorial Classes

2015
This paper presents a laboratorial curricular unit program running in the 1st semester, 4th year of the Integrated Master in Industrial Electronics at the University of Minho. In Project I curricular unit, students designed, developed and implemented an inverted pendulum platform where different control algorithms were tested.

A Class of Projective Transformations for Linear Programming

SIAM Journal on Computing, 1990
A class of projective transformations under which potential functions are invariant for linear programming is described. As a result, a new projective algorithm converging in $O(L\sqrt n)$ iterations is developed. The algorithm does not require centering conditions, and its convergence speed is improved by a factor $\sqrt n $ over Karmarkar’s ...
