Finite-sample certification and operating envelopes for spectral clustering and graph centrality
Chandrasekhar Gokavarapu, Sekhar Babu Gosala, Rajeev Muthu +3
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, D. Madhusudhana Rao +4
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…
