A note on orbit categories, classifying spaces, and generalized homotopy fixed points

, 2017
We give a new description of Rosenthal’s generalized homotopy fixed point spaces as homotopy limits over the orbit category. This is achieved using a simple categorical model for classifying spaces with respect to families of ...

Homotopy Methods to Compute Equilibria in Game Theory

This paper presents a complete survey of the use of homotopy methods in game theory.Homotopies allow for a robust computation of game-theoretic equilibria and their refinements.

Inverse systems of spectra and generalizations of a theorem of W.H. Lin [PDF]

In this thesis we generalize a theorem of W. H. Lin. Lin's results are concerned with the homotopy and cohomotopy of an inverse system of spectra {P-k }.

A new modification of the homotopy perturbation method [PDF]

, 2010
In this paper, a new modification of the homotopy perturbation method (HPM) is presented and applied to linear ordinary differential equations and nonlinear differential equations. A comparative study between the new modified homotopy perturbation method

Singular Cochains and rational Homotopy Type

, 2004
Rational homotopy types of simply connected topological spaces have been classified by weak equivalence classes of commutative cochain algebras (Sullivan) and by isomorphism classes of minimal commutative $A_{infty}$-algebras (Kadeishvili).

A note on homotopy and pseudoisotopy of diffeomorphisms of $4$-manifolds

Comptes Rendus. Mathématique
This note serves to record examples of diffeomorphisms of closed smooth $4$-manifolds $X$ that are homotopic but not pseudoisotopic to the identity, and to explain why there are no such examples when $X$ is orientable and its fundamental group is a free ...

The C_2 effective spectral sequence and the homotopy of ko_{C_2}

, 2020
By work of Voevodsky, the slice filtration in motivic homotopy theory provides a powerful tool for computing homotopy groups of motivic spectra. In this talk, I will describe the motivic slice filtration and the effective slice spectral sequence it ...

An interior point algorithm for computing equilibria in economies with incomplete asset markets [PDF]

, 2004
Computing equilibria in general equilibria models with incomplete asset (GEI) markets is technically difficult. The standard numerical methods for computing these equilibria are based on homotopy methods.

INDEX COMPUTATION OF SOME BISINGULAR OPERATORS WITH SHIFT BY HOMOTOPY METHOD

Advanced Engineering Research, 2010
The work continues to research the insufficiently explored problem of bisingular operators with shift index. It considers new cases of index computation of the bisingular operators with indisintegrative involutive shift by the homotopy method.
