we mainly focus on the derivation of a flexible condition number for weighted linear least squares problem.With the Fréchet derivative and kronecker produc
This report proves that a class of congruence equations has no solutions using mathematical induction.If so,then Twin Primes Conjecture is true,i.e.there ar
We have firstly defined a new error formulation and presented a method to solve an over determined linear system of equations with multiple right-hand side
Information flow/transfer the widely applicable physical notion can be rigorously derived from first principles,rather than axiomatically proposed as an ans
We are interested in alloys that undergo a martensitic phase transition of the cubic-to-tetragonal symmetry breaking,which we study variation-ally based on
