measure data, which satisfy conservation laws of mass, momentum, and energy, despite being measure solutions. This happens to solve, even with general data, the 1D measure solution case of an open problem regarding the conservation law of the Vlasov-Poisson equation raised by Diperna and Lions....
An article in Scientific America has pointed out that empirical research says that, actually, you think you're more beautiful than you are. We have a deep-seated need to feel good about ourselves and we naturally employ a number of self-enhancing strategies to research into what the call the...
In this scenario, the strong force acquires a more complex structure, which includes the usual color sector and an enlarged strong exceptional dynamics, due to six residual generators of exceptional G(2), which might gain mass via a symmetry breaking: to recover standard SU(3) color strong ...
