Fixed point theory on extension-type spaces and essential maps on topological spaces [PDF]
Fixed Point Theory and Applications, 2004 We present several new fixed point results for admissible self-maps in extension-type spaces. We also discuss a continuation-type theorem for maps between topological spaces.

Essential maps and coincidence principles for general classes of maps
Filomat, 2017 We introduce the notion of an essential map for a general class of maps. In addition we present homotopy and normalization type properties for these maps. To the memory of Professor Lj. Ćirić (1935–2016)

Coincidence type alternatives for Φ --essential maps
, 2016 In this paper we present some criteria for Φ-essential maps and as a consequence these generate a number of new Leray-Schauder type alternatives. c ©2016 All rights reserved.

NONLINEAR ESSENTIAL MAPS OF MONCH, 1-SET CONTRACTIVE DEMICOMPACT AND MONOTONE (S)+ TYPE [PDF]
, 2001 In this paper the notion of an essential map is extended to a wider class of maps. Here we show if F is essential and F≅G, then G has a fixed point.

Bayesian analysis of retinotopic maps
eLife, 2018 Human visual cortex is organized into multiple retinotopic maps. Characterizing the arrangement of these maps on the cortical surface is essential to many visual neuroscience studies. Typically, maps are obtained by voxel-wise analysis of fMRI data. This

A Dynamic Points Removal Benchmark in Point Cloud Maps [PDF]
2023 IEEE 26th International Conference on Intelligent Transportation Systems (ITSC), 2023 In the field of robotics, the point cloud has become an essential map representation. From the perspective of downstream tasks like localization and global path planning, points corresponding to dynamic objects will adversely affect their performance ...
