We define united K-theory for real C*-algebras, generalizing Bousfieldâ€™s topological united K-theory. United K-theory incorporates three functors â€” real K-theory, complex K-theory, and self-conjugateâ€¦ (More)

We prove that the united K-theory functor is a surjective functor from the category of real simple purely infinite C*-algebras to the category of countable acyclic CRT-modules.

Laser-induced breakdown spectroscopy (LIBS) was carried out on twenty-three low to high alloy steel samples to quantify their concentrations of chromium, nickel, and manganese. LIBS spectral dataâ€¦ (More)

We define united KK-theory for real C*-algebras A and B such that A is separable and B is Ïƒ-unital, extending united K-theory in the sense that KKCRT (R, B) = KCRT (B). United KK-theory containsâ€¦ (More)

We prove that all eight KO groups for a real C-algebra can be constructed from homotopy classes of unitary matrices that respect a variety of symmetries. In this manifestation of the KO groups, allâ€¦ (More)

We classify real Kirchberg algebras using united Ktheory. Precisely, let A and B be real simple separable nuclear purely infinite C*-algebras that satisfy the universal coefficient theorem such thatâ€¦ (More)
