Pankaj K. Agarwal

Pankaj K. Agarwal is a mathematics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Pankaj K. Agarwal rather than just read about it. In short: Pankaj Kumar Agarwal is an Indian computer scientist and mathematician researching algorithms in computational geometry and related areas. He is the RJR Nabisco Professor of Computer Science and Mathematics at Duke University, where he has been chair of the computer science department since 2004.

Key takeaways

  • Pankaj K. Agarwal belongs to mathematics; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Pankaj K. Agarwal to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Pankaj K. Agarwal from memory before moving on to harder problems.

Reference excerpt

Pankaj Kumar Agarwal is an Indian computer scientist and mathematician researching algorithms in computational geometry and related areas. He is the RJR Nabisco Professor of Computer Science and Mathematics at Duke University, where he has been chair of the computer science department since 2004. He obtained his Doctor of Philosophy (Ph.D.) in computer science in 1989 from the Courant Institute of Mathematical Sciences, New York University, under the supervision of Micha Sharir.

Books Agarwal is the author or co-author of:

Intersection and Decomposition Algorithms for Planar Arrangements (Cambridge University Press, 1991, ISBN 978-0-521-40446-4). The topics of this book are algorithms for, and the combinatorial geometry of, arrangements of lines and arrangements of more general types of curves in the Euclidean plane and the real projective plane. The topics covered in this monograph include Davenport–Schinzel sequences and their application to the complexity of single cells in arrangements, levels in arrangements, algorithms for building arrangements in part or in whole, and ray shooting in arrangements. Davenport–Schinzel Sequences and Their Geometric Applications (with Micha Sharir, Cambridge University Press, 1995, ISBN 978-0-521-47025-4). This book concerns Davenport–Schinzel sequences, sequences of symbols drawn from a given alphabet with the property that no subsequence of more than some finite length consists of two alternating symbols. As the book discusses, these sequences and combinatorial bounds on their length have many applications in combinatorial and computational geometry, including bounds on lower envelopes of sets of functions, single cells in arrangements, shortest paths, and dynamically changing geometric structures. Combinatorial Geometry (with János Pach, Wiley, 1995, ISBN 978-0-471-58890-0). This book, less specialized than the prior two, is split into two sections. The first, on packing and covering problems, includes topics such as Minkowski's theorem, sphere packing, the representation of planar graphs by tangent circles, the planar separator theorem. The second section, although mainly concerning arrangements, also includes topics from extremal graph theory, Vapnik–Chervonenkis dimension, and discrepancy theory.

Awards and honors Agarwal was elected as a fellow of the Association for Computing Machinery in 2002. He is also former Duke Bass Fellow and an Alfred P. Sloan Fellow. He was the recipient of a National Young Investigator Award in 1993. Before holding the RJR Nabisco Professorship, he was the Earl D. Mclean Jr. Professor of Computer Science at Duke.

Worked examples

Example 1 — a first encounter with Pankaj K. Agarwal

Start with the simplest possible case. Write down what Pankaj K. Agarwal claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In mathematics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Pankaj K. Agarwal before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Pankaj K. Agarwal ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Pankaj K. Agarwal

In research
Pankaj K. Agarwal appears in mathematics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Pankaj K. Agarwal in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Pankaj K. Agarwal is common in secondary-school and first-year university syllabi. It links to neighbouring topics 20th-century Indian mathematicians, Courant Institute of Mathematical Sciences alumni, Duke University faculty, so understanding it makes those chapters shorter.
In everyday life
Look for Pankaj K. Agarwal outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
