Abstract: The well-known fact following from the Holmgren-John-Tataru uniqueness theorem is a local approximate boundary L2-controllability of the dynamical system governed by the wave equation. Generalizing this result, we establish the controllability in certain classes of… read more here.

DOI: 10.3390/sym15010246
Abstract: A new (p,q)-integral identity involving left and right post quantum derivatives, by using three times (p,q)-differentiable functions is established and then this identity is used to derive several new post-quantum Ostrowski type integral inequalities for… read more here.
