Trung Tuyen Truong

DISCLAIMER: What written on this website reflects only my opinion, and not the opinion of my employer(s).

(My name in native language is Trương Trung Tuyến. Trương is the surname (usually has no meaning, about 2.2% of Vietnamese have this surname), while Trung Tuyến together has this meaning: https://en.wikipedia.org/wiki/Median_(geometry) Informally, I am called "Tuyến", which sounds like "Twain" in Mark Twain.)

Since September 2023, I am a Professor of Mathematics at University of Oslo. From September 2017-September 2023, I was an Associate Professor of Mathematics at University of Oslo.

I am very excited to work here at University of Oslo, with a long tradition of strong research and teaching, where Niels Henrik Abel used to be. My research is in Several Complex Variables, Dynamical Systems and related topics in Algebraic Geometry. I am also keen to applications of these fields. Originally from Vietnam, I traveled all around the world studying and working : Indiana University (USA) PhD, 2006-2012, under the supervision of Professor Eric Bedford; Syracuse University (USA), Postdoc, 2012 - 2014; Korea Institute for Advanced Study (South Korea), Postdoc, 2014-2015; and The University of Adelaide (Australia), Postdoc 2015 - 2017; before coming here to Oslo. My PhD dissertation was on pullback of positive closed currents by meromorphic maps.

Deep Learning/Optimization/Root finding/Computational techniques in Practical Life: Understanding and appreciating the power of Deep Learning/Optimization/Root finding techniques to solve many difficult practical questions in real life and science/education (including robotics, electric car battery, AI,... ),

I and my team are developing softwares: 1. to help high school and university students learn mathematics and optimization and 2. to provide efficient computing tools.

Check our Optimization/Root finding/Computational techniques app: nuvoptimization.com [One remarkable fact, will be discussed in a video, is that a question in a book by some Princeton University authors proposed a wrong solution, and Matlab, IPOPT,... found solutions much less optimal than those found by NUV Optimization solvers. ]

Another project, which I am collaborating with AI companies and medical doctors, is to use AI to help doctors with diagnosing from lung data measurement (like spirometry data...)

Some main research themes and results:

Some of the topics I like to get resources to work on are: relations between Weil's Riemann hypothesis and standard conjectures and dynamical systems, Riemann hypothesis itself, the Jacobian conjecture, Newton's method type and other iterative methods in root finding and optimization. A common theme is my enthusiasm in applying Dynamical systems theory and computers (including coding and Machine Learning/Deep Learning/AI) into solving problems, both in pure theory and in real life applications.

Some favourite quotes:

Who hopes for what he already has? But if we hope for what we do not yet have, we wait for it patiently. (The Bible)

For what shall it profit a man, if he shall gain the whole world, and lose his own soul? (The Bible)

There is no way to happiness. Happiness is the way. (The Buddha)

Now, Kalamas, don't go by reports, by legends, by traditions, by scripture, by logical conjecture, by inference, by analogies, by agreement through pondering views, by probability, or by the thought "This contemplative is our teacher." When you know for yourselves that "These qualities are skilful; these qualities are blameless; these qualities are praised by the wise; these qualities, when adopted and carried out, lead to welfare and to happiness"- then you should enter and remain in them. (The Buddha)

A foolish faith in authority is the worst enemy of truth. (Albert Einstein)

All truths are easy to understand once they are discovered; the point is to discover them. (Galileo Galilei)

Live as if you were to die tomorrow. Learn as if you were to live forever. (Mahatma Gandhi)

Your time is limited, don't waste it living someone else's life. Don't be trapped by dogma, which is living the result of other people's thinking. Don't let the noise of other opinions drown you own inner voice. And most important, have the courage to follow your heart and intuition, they somehow know what you truly want to become. Everything else is secondary. (Steve Jobs)

That's been one of my mantras - focus and simplicity. Simple can be harder than complex; you have to work hard to get your thinking clean to make it simple. But it's worth it in the end because once you get there, you can move mountains. (Steve Jobs)

A lot of companies have chosen to downsize, and may be that was the right thing for them. We chose a different path. Our belief was that if we kept putting great products in front of customers, they would continue to open their wallets. (Steve Jobs)
