In other words, transport occurs with finite speed: that makes a great difference with the instantaneous positivity of solution (related of a “infinite speed” of propagation

In 1979, Ejiri [Eji79] obtained the following rigidity theorem for n( ≥ 4)- dimensional oriented compact simply connected minimal submanifolds with pinched Ricci curvatures in

First introduced by Faddeev and Kashaev [7, 9], the quantum dilogarithm G b (x) and its variants S b (x) and g b (x) play a crucial role in the study of positive representations

(9) Next, we will set up an aggregation-diffusion splitting scheme with the linear transport approximation as in [6] and provide the error estimate of this method.... As a future

For general n ≥ 2, G n was first studied by Chai, Wang and the second author [4] from the viewpoint of algebraic geometry. Among other things, they established the

We prove that arbitrary actions of compact groups on finite dimensional C ∗ -algebras are equivariantly semiprojec- tive, that quasifree actions of compact groups on the Cuntz
