computational complexity presents outstanding research in computational complexity. Its subject is at the interface between mathematics and theoretical computer science, with a clear mathematical profile and strictly mathematical format.The central topics are:Models of computation, complexity bounds (with particular emphasis on lower bounds), complexity classes, trade-off resultsfor sequential and parallel computationfor "general" (Boolean) and "structured" computation (e.g. decision trees, arithmetic circuits)for deterministic, probabilistic, and nondeterministic computationworst case and average caseSpecific areas of concentration include:Structure of complexity classes (reductions, relativization questions, degrees, derandomization)Algebraic complexity (bilinear complexity, computations for polynomials, groups, algebras, and representations)Interactive proofs, pseudorandom generation, and randomness extractionComplexity issues in:learning theorynumber theorylogic (complexity of logical theories, cost of decision procedures)combinatorial optimization and approximate Solutionsdistributed computingproperty testing
