We prove that time evolution of a linear analytic initial value problem leads to sectorial holomorphic solutions in time.

Rapid economic and population growth has led to increased demand for water from the industrial and domestic sectors and put pressure on resources available for agricultural production. With growing scarcity and increasing inter-sectorial competition for water the need for efficient and sustainable water allocation policies has also become more important. Finding ways to meet this growing demand...

We prove that a sectorial operator admits an H∞functional calculus if and only if it has a functional model of NagyFoiaş type. Furthermore, we give a concrete formula for the characteristic function (in a generalized sense) of such an operator. More generally, this approach applies to any sectorial operator by passing to a different norm (the McIntosh square function norm). We also show that th...

La ecoendoscopia sectorial es una técnica muy segura con una gran precisión diagnóstica no alcanzable por otras exploraciones utilizadas en la estadificación de distintos tumores del tracto digestivo y órganos vecinos. Permite la realización de punción aspiración con aguja fina con obtención de material para estudio histológico, además de facilitar la realización de numerosas maniobras terapéut...

If A,B are sectorial operators on a Hilbert space with the same domain and range, and if �Ax� ≈ �Bx� and �A−1x� ≈ �B−1x�, then it is a result of Auscher, McIntosh and Nahmod that if A has an H ∞−calculus then so does B. On an arbitrary Banach space this is true with the additional hypothesis on B that it is almost R-sectorial as was shown by the author, Kunstmann and Weis in a recent preprint. ...

Ever since the Government of India established the “National Knowledge Commission” under the chairmanship of Pitroda[1] to promote awareness of the significance of the growth of knowledge in developing a knowledge-based society, continued efforts have been made to generate new ideas and innovations in different sectors of knowledge. Establishment of a National Innovation Council was a first ste...

This paper aims to analyse the economy-wide implications of a carbon tax applied on the Chilean electricity generation sector. In order to analyse the macroeconomic impacts, both an energy sectorial model and a Dynamic Stochastic General Equilibrium model have been used. During the year 2014 a carbon tax of 5 US$/tCO2e was approved in Chile. This tax and its increases (10, 20, 30, 40 and 50 US$...
