A formula is a read-once formula if each variable appears at most once in it. An arithmetic read-once formula (AROF) with exponentiation is one in which the operations are addition, substraction,… (More)

We give two harmonic mappings of the open unit disc onto bounded convex domains that extend continuously to the unit circle as 2-valent local homeomorphisms onto the boundary of the image domains… (More)

The problem of mapping the interior of a Jordan polygon univalently by the Poisson integral of a step function was posed by T. Sheil-Small (1989). We describe a simple solution using “ear clipping”… (More)

Properties of John functions in Nehari-type classes Sarita Agrawal Indian Institute of Technology Indore, India e-mail: saritamath44@gmail.com In this paper we introduce the notion of John functions… (More)

Jeffreys and Shtarkov distributions play an important role in universal coding andminimumdescription length (MDL) inference, two central areas within the field of information theory. It was recently… (More)

We consider graphs of solutions to the minimal surface equation which are unbounded over subarcs of the domain boundary. An extensive study of such surfaces was made by Jenkins and Serrin. In this… (More)

The aim of this work is to answer positively a more general question than the following which is due to T. Sheil-Small: Does the harmonic extension in the open unit disc of a mapping f from the unit… (More)
