Hello, I've been having difficulties running a system with noncollinear magnetism using a fully relativistic ECP and hybrid DFT functional. While I can achieve convergence for non-hybrid DFT, the code crashes for hybrids with the mentioned error in the title. I checked for some possible culprit...

In the present paper, the positive definite solutions for the nonlinear matrix equation $X-A^{*}X^{-s}A-B^{*}X^{-t}B=I$, where $s,tin(0,1]$ are studied. The convergence of the proposed iterative methods are discussed. The necessary and sufficient conditions of the existence of ...
I stumbled upon an issue when solving a symmetric positive definite system using trsv. The matrix is already factorized, the issue is with the solution - trsv with a transposed factor followed by another trsv. The second trsv segfaults in a very specific si...
