We study new classes of linear preservers between C-algebras and between JB-triples. Let E and F be JB-triples with e(E1). We prove that every linear map T:EF strongly preserving Brown–Pedersen quasi-invertible elements is a triple homomorphism. Among the consequences, we establish that, given two unital C-algebras A and B, for each linear map T strongly preserving Brown–Pedersen quasi-invertible elements, there exists a Jordan -homomorphism S:AB satisfying T(x)=T(1)S(x) for every xA. We also study the connections between linear maps strongly preserving Brown–Pedersen quasi-invertibility and other clases of linear preservers between C-algebras like Bergmann-zero pairs preservers, Brown–Pedersen quasi-invertibility preservers, and extreme points preservers.
