In our method, the geometric and photometric transformations are jointly parameterized by their corresponding Lie algebras. Based on this parameterization approach, the second-order approximation ...

The Dalai Lama believed that he should be succeeded by a democratic leader elected by Tibetans.

A good simile is that Mr. Trump put a pot of water on the stove, told Iran to jump in, put the lid over them, then smiled, turned up the heat — and will now let them stew. As postbellum realities now ...

A Gröbner-Shirshov basis for the Lie algebra A n, abstractly defined by generators h i, x i, y i, i=1,..., n and the Serre relations for the Cartan matrix A n, over a field k of characteristic ≠2 is ...
