Research description

My research focuses on establishing frameworks for the study of the closeness of signals and structures on triangulated finite bounded surface regions on planar and curved surfaces in a space K endowed with an adjacency or spatial or descriptive proximity relation. Regions E in K are strongly close, provided the interiors of E overlap or have matching descriptions. In Alexandroff-Hopf-Whitehead CW (Closure finite Weak) complexes on K, e.g., this leads to the discovery of proximal sub-complexes and proximal nerve structures that are close to each other either spatially or descriptively. Of particular interest is the detection, characterization, analysis, measurement, rate of change, energy, and classification of shapes of nesting, non-overlapping skeletal vortexes, forming what are known as optical vortex nerves.
