Many historians consider the 1926/27 PKI Uprisings as important precursors of Indonesia’s nationalist movement, which ultimately led to the country’s independence. When it comes to the actual course of events, however, existing narratives tend to describe the abortive revolts as ill-prepared, poorly organised and easily suppressed – and consequently, of limited impact in shaking the foundation of the Dutch colonial regime. It is also commonly understood that in the aftermath of the rebellions, dutch authorities dealt a crushing blow to the pki and its associated organisations by carrying out large-scale arrests, imprisonments, executions, and banishments. Beyond these facts, however, very little attention has been paid to the deeper meanings that the revolt revealed. as the following sections will demonstrate, the movement created enormous anxiety in the NEI which forced the Dutch colonial government to act with a strong hand. moreover, with frequent exchanges of information and personnel across the Malacca Straits, the NEI uprisings also generated considerable uneasiness in British Malaya.

It is shown that relativistic many-body Hamiltonians and wave functions can beexpressed systematically with Tracy-Singh products for partitioned matrices. The latter gives rise to the usual notion for a relativistic $N$-electron wave function: A column vector composed of $2^N$ blocks, each of which consists of $2^N$ components formed by the Kronecker products of $N$ one-electron 2-spinors. Yet, the noncommutativity of the Tracy-Singh product dictates that the chosen serial ordering of electronic coordinates cannot be altered when antisymmetrizing a Tracy-Singh product of 4-spinors. It is further shown that such algebraic representation uncovers readily the internal symmetries of the relativistic Hamiltonians and wave functions, which are crucial for deriving the electron-electron coalescence conditions.
The electron-electron coalescence conditions for the wave functions of the Dirac-Coulomb (DC), Dirac-Coulomb-Gaunt (DCG), and Dirac-Coulomb-Breit (DCB) Hamiltonians are analyzed by making use of the internal symmetries of the reduced two-electron systems. The results show that, at the coalescence point of two electrons, the wave functions of the DCG Hamiltonian are regular, while those of the DC and DCB Hamiltonians have $r_{12}^{\nu}$ type weak singularities, with $\nu$ being negative and of $\mathcal{O}(\alpha^2)$. Yet, such asymptotic expansions of the relativistic wave functions are only valid within an extremely small convergence radius $R_c$ of $\mathcal{O}(\alpha^2)$. Beyond this radius, the behaviors of the relativistic wave functions are still dominated by the nonrelativistic limit.
The fundamental problems inherent in relativistic explicit correlation are highlighted, with practical suggestions for guiding future development of relativistic explicitly correlated wave function methods.
