This volume is dedicated to the eminent Georgian mathematician Roland Duduchava on the occasion of his 70th birthday. It presents recent results on Toeplitz, Wiener-Hopf, and pseudodifferential operators, boundary value problems, operator theory, approximation theory, and reflects the broad spectrum of Roland Duduchava's research. The book is addressed to a wide audience of pure and applied mathematicians.

Presents papers written by internationally leading researchers Shares a broad picture of the current research in operator theory and partial differential equations Motivates further research in a wide variety of fields in Mathematical Analysis and its applications
