there are many application papers that solve elliptic boundary value problems by meshless methods, and they use various forms of generalized stiffness matrices that approximate derivatives of functions from values at scattered nodes $ x _ 1, \ ldots, x _ m \ in \ omega \ subset \ r ^ d $. if $ u ^ * $ is the true solut... | arxiv:1612.07550 |
i investigate production and decay of heavy neutral gauge bosons z ' in gut - inspired u ( 1 ) ' groups and in the sequential standard model. in particular, decays into supersymmetric particles, such as slepton, chargino and neutralino pairs, as predicted in the mssm, are accounted for, with a special interest in final... | arxiv:1307.1040 |
