Reference excerpt

Pietro G. Frè (born 1952) is an Italian theoretical physicist and an emeritus full professor of the University of Turin.

Early life and education Pietro G. Frè was born in Alessandria, Italy in 1952.

Career Frè was a fellow at the Theoretical Division of CERN, a post-doctoral fellow at the California Institute of Technology and Bielefeld University in the early years of his career. He was an associate professor at the University of Turin, a full professor at the International School for Advanced Studies for six years, and, since 1996, a full professor at the University of Turin as the chair of general relativity. From 2009 to 2017 he was the scientific counselor of the Italian Embassy in Moscow. From 1996 to 2000 he was president of SIGRAV (Italian Society of General Relativity and Physics of Gravitation), and from 2017 to 2021 he was director of the Arnold Regge Center of Theoretical Physics.

Contributions Among his major contributions in theoretical physics, of particular note are the introduction of the rheonomic formulation of supergravity (with R. D'Auria), the independent invention under the name of "Cartan Integrable Systems" of Free Differential Algebras and their extension with fermionic p-forms, the D'Auria-Frè algebra, later evolved into the L-infinity algebras, the geometric formulation of the eleven-dimensional supergravity (low-energy limit of M-theory), the geometric systematization of the N=2 Supergravity lagrangian (with S. Ferrara et al.), the introduction of the embedding matrix formulation of maximal gauged sueprgravity, later evolved in the embedding tensor formulation of extended supergravities, the discovery of some of the homogeneous Sasakian manifolds in seven dimensions and the first development of their holographic equivalents by quivers. In recent years Pietro Frè has made original research in the context of Kronheimer construction and McKay quivers.

Essays and Literature Pietro Frè is also an essay and novel writer. He has published a few novels in Italian and essays on the history of mathematical conceptions and an essay on the history of Ukraine and Russia.

Worked examples

Example 1 — a first encounter with Pietro G. Frè

Start with the simplest possible case. Write down what Pietro G. Frè claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Pietro G. Frè before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Pietro G. Frè ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Pietro G. Frè

In research: Pietro G. Frè appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Pietro G. Frè in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Pietro G. Frè is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1952 births, 21st-century Italian male novelists, 21st-century Italian novelists, so understanding it makes those chapters shorter.
In everyday life: Look for Pietro G. Frè outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
