Konrad Osterwalder (born June 3, 1942) is a Swiss mathematician and physicist, former Undersecretary-General of the United Nations, former Rector of the United Nations University (UNU),[1] and Rector Emeritus of the Swiss Federal Institute of Technology Zurich (ETH Zurich).

United Nations University

Rector Osterwalder was appointed to the position of United Nations Under Secretary General and United Nations University Rector by United Nations Secretary-General Ban Ki-moon May 2007[2] and served until 28 February 2013. He succeeded Prof. Hans van Ginkel from the Netherlands to be the fifth Rector of the United Nations University.

He is credited with turning United Nations University into a world leading institution, ranked #5 & #6 in two categories according to the 2012 Global Go to Think Tank Rankings.[3] He was responsible for ensuring that UNU's charter was amended by the United Nations General Assembly[4] in 2009 allowing the United Nations University to grant degrees, introducing UNU's degree programmes and creating a new concept in education, research and development by introducing the twin institute programmes. A concept that is changing the way that development, aid and capacity building is approached both by developed countries and developing and least developed countries.

Bologna Process

In March 2000, following the Bologna Declaration by 28 European Education Ministers, the European University Association and the Comite de Liaison within the National Rector's Conference convened the Convention of European Higher Education in salamanca Spain, hereinafter referred to as the "Salamanca Process"with the aim of discussing the Bologna Declaration and delivering an overall, univocal response to the Council of Ministers. Professor Osterwalder, Rector of ETH, was chosen by the conference as the Rapporteur of the Salamanca Process and the voice of Higher Education institutions. The meeting concluded with a declaration and a report that led to the basis of Higher Education reform within the Bologna process and the EU. In addition, the two conveners of the conference formed the European University Association.

Life and career

Konrad Osterwalder was born in Frauenfeld, Thurgau, Switzerland, in June 1942. He studied at the Swiss Federal Institute of Technology (Eidgenössische Technische Hochschule; ETH) in Zurich, where he earned a Diploma in theoretical physics in 1965 and a Doctorate in theoretical physics in 1970.

After one year with the Courant Institute of Mathematical Sciences, New York University, he accepted a research position at Harvard University in 1971. He remained on the faculty of Harvard for seven years, and was promoted to Assistant Professor for Mathematical Physics in 1973 and Associate Professor for Mathematical Physics in 1976. In 1977, he returned to Switzerland upon being appointed a full Professor for Mathematical Physics at ETH Zurich.

During his tenure at ETH Zurich, Rector Osterwalder served as Head of the Department of Mathematics (1986–1990) and Head of the Planning Committee (1990–1995), and was founder of the Centro Stefano Franscini seminar center in Ascona. He was appointed Rector of ETH in 1995 and held that post for 12 years. From November 2006 through August 2007, he also served concurrently as ETH President pro tempore.

On 1 September 2007, Rector Osterwalder joined the United Nations University as its fifth rector. In that role, he held the rank of Under-Secretary-General of the United Nations.

Rector Osterwalder's research focused on the mathematical structure of relativistic quantum field theory as well as on elementary particle physics and statistical mechanics. During his long and distinguished career, he has been a Visiting Fellow/Guest Professor at several prominent universities around the world, including the Institut des Hautes Études Scientifiques (IHES; Bures-sur-Yvette, France); Harvard University; University of Texas (Austin); Max Planck Institute for Physics and Astrophysics (Munich), Università La Sapienza (Rome); Università di Napoli; Waseda University; and Weizmann Institute of Science (Rehovot, Israel).

Since 2014 - member of International Scientific Council of Tomsk Polytechnic University.[5]

Osterwalder–Schrader theorem

The Osterwalder–Schrader theorem states that Schwinger functions that satisfy certain properties can be analytically continued into a quantum field theory.

Suppose Euclidean path integrals satisfy reflection positivity formally. Let F be any polynomial functional of the field φ which does not depend upon the value of φ(x) for those points x whose τ coordinates are nonpositive. Then

 \int \mathcal{D}\phi F[\phi(x)]F[\phi(\bar{x})]^* e^{-S[\phi]}=\int \mathcal{D}\phi_0 \int_{\phi_+(\tau=0)=\phi_0} \mathcal{D}\phi_+ F[\phi_+]e^{-S_+[\phi_+]}\int_{\phi_-(\tau=0)=\phi_0} \mathcal{D}\phi_- F[\bar{\phi}_-]^* e^{-S_-[\phi_-]}.

Since the action S is real and can be split into S+, which only depends on φ on the positive half-space, and S− which only depends upon φ on the negative half-space, and if S also happens to be invariant under the combined action of taking a reflection and complex conjugating all the fields, then the previous quantity has to be nonnegative.
