Algebraic topology. Specific Special interests include homotopy and fiber spaces
My field of interest is within the area of algebraic topology, called homotopy theory. Roughly, it is a study of deformation from one topological space to another. Homotopy fiber is a part of a construction that associates a fibration to an arbitrary continuous function of topological spaces. The concept of fiber space is crucial in homotopy theory.
