[[File:Jenny Harrison.jpegthumbrightJenny Harrison]]'''Jenny Harrison''' is a professor of mathematics at [[UC Berkeley]]. She specializes in [[geometric analysis]] and areas in the intersection of [[algebra]], [[geometry]], and [[geometric measure theory]]. Her most important contribution to mathematics has come in recent years when she developed a theory of operator calculus that unifies an infinitesimal calculus with the classical theory of the smooth continuum, a long outstanding problem.<ref>[http://arxiv.org/abs/1101.0979] Operator Calculus  the Exterior Differential Complex, arXiv posting January 2011, 89 pages</ref> The infinitesimals are constructive and arise from methods of standard analysis, as opposed to the nonstandard analysis of [[Abraham Robinson]]. The methods apply equally well to a large class of domains called [[differential chains]] which place soap films, fractals, and charged particles, on the same footing as smooth submanifolds. The results include optimal generalizations and simplifications of the theorems of Stokes, Gauss and Green. She is also known for her counterexamples to the [[Denjoy conjecture]] and a version of the [[Seifert conjecture]]. She has pioneered applications of operator calculus (called chainlet geometry in<ref>[http://www.citebase.org/fulltext?format=application%2Fpdf&identifier=oai%3AarXiv.org%3Amathph%2F0501001] Lecture notes on chainlet geometry  new topological methods in geometric measure theory, arXiv posting May 24, 2005, 153 pages, Proceedings of the Ravello Summer School for Mathematical Physics, 2005</ref>) to the calculus of variations,<ref>[http://arxiv.org/abs/1106.5839] Solution to Plateau's Problem, submitted to the Annals of Mathematics, March 2010</ref> physics, and numerical analysis.

Harrison grew up in Tuscaloosa, Alabama. Her graduate studies were at the [[University of Warwick]], where [[E.C. Zeeman]] introduced her to Plateau's Problem. [[Hassler Whitney]] was her postdoctoral adviser at the [[Institute for Advanced Study]]. After her time at the Institute, she became an instructor at [[Princeton University]]. She found a counterexample to the Seifert conjecture while on the faculty at [[Oxford University]]. She was struck by the duality between differentiability class of functions, and Hausdorff dimension of domains manifested in her work, as well as Sard's Theorem and Denjoy's Theorem, and observed, "The smoother the function, the rougher can be the domains in many contexts." In a Berkeley seminar in 1983 she proposed the existence of a general theory linking these together, and Operator Calculus began to evolve.

Jenny Harrison and Harrison Pugh recently proved that Operator Calculus is distinct from the theory of Schwartz [[distribution (mathematics)distribution]]s and de Rham [[current (mathematics)current]]s, settling a question posed by [[Michael Atiyah]] in 1996. Furthermore, their paper<ref>[http://arxiv.org/abs/1101.0383] Topological Aspects of Differential Chains, to appear in the Journal of Geometric Analysis, 2011</ref> showed the topological vector space of differential chains is uniquely determined by four simple axioms.

I removed a lot of totally unverified claims and extraneous information. Essentially this is a nonnotable mathematician who has a lot of stuff on her page that shouldn't be there. I pared it down to what was important  her lawsuit
