1973-. American computer scientist and entrepreneur.
Co-invented PageRank with Sergey Brin (1998), applying eigenvalue analysis of link graphs to rank web search results by structural importance rather than content frequency.
Co-founded Google, building the infrastructure that made graph-based search the dominant paradigm.
His insight that links are votes — and that the weight of a vote depends on the voter's own importance — is a recursive definition that converges under the Perron-Frobenius theorem.
cyber extends this idea: cyberlinks are weighted edges in a knowledge graph, and cyberank computes the stationary focus distribution across all particles.
