Morita Transport, Marked Projective Loci, and Dedekind Classification for C4-Type Conditionss
Chandrasekhar Gokavarapu, Sekhar Babu Gosala, Sudhakar Gadde +2
Objectwise Morita invariance of $\Cfour$ is known. We prove the corresponding statements for $\Cfourstar$, semi-weak-CS, and strongly $\Cfourstar$, including the chain joins in the…

Finite-sample certification and operating envelopes for spectral clustering and graph centrality
Chandrasekhar Gokavarapu, Sekhar Babu Gosala, Rajeev Muthu +2
Spectral clustering and node rankings are commonly reported from one observed network without a finite-sample statement of what the observation supports. We develop a certification…

Finite diagonalizable torsors and Kummer cohomology over semiring schemes
Chandrasekhar Gokavarapu, Sajani Lavanya Madasi, Rajeev Muthu +2
Classical descent treats a finite diagonalizable torsor as a higher-rank locally free object. Over semirings that route is incomplete: fpqc-local freeness is not known to imply Zar…
