WebThe book offers a comprehensive introduction to Leavitt path algebras (LPAs) and graph C*-algebras. Highlighting their significant connection with classical K-theory—which plays an important role in mathematics and its related emerging fields—this book allows readers from diverse mathematical backgrounds to understand and appreciate these structures. Webpath algebras L(E) and L(F) are graded Morita equivalent if, and only if, the graph C∗-algebras C∗(E) and C∗(F) are equivariant Morita equivalent. Proof. Suppose that the …
