Overview

What is he best known for?

The fields of study he is best known for:

  • Mathematical analysis
  • Algebra
  • Hilbert space

His scientific interests lie mostly in Modulation space, Mathematical analysis, Pure mathematics, Algorithm and Time–frequency analysis. His Modulation space study combines topics in areas such as Discrete mathematics, Operator theory and Bounded function. As a part of the same scientific family, Karlheinz Gröchenig mostly works in the field of Mathematical analysis, focusing on Function and, on occasion, Convolution and Kernel method.

Karlheinz Gröchenig interconnects Class, Besov space and Wavelet in the investigation of issues within Pure mathematics. His biological study spans a wide range of topics, including Frame and Hilbert space. Karlheinz Gröchenig usually deals with Time–frequency analysis and limits it to topics linked to Harmonic analysis and Algebra over a field and Theoretical physics.

His most cited work include:

  • Foundations of Time-Frequency Analysis (1993 citations)
  • Banach spaces related to integrable group representations and their atomic decompositions, I (671 citations)
  • Banach spaces related to integrable group representations and their atomic decompositions, I (671 citations)

What are the main themes of his work throughout his whole career to date?

Karlheinz Gröchenig spends much of his time researching Pure mathematics, Mathematical analysis, Modulation space, Discrete mathematics and Combinatorics. The various areas that Karlheinz Gröchenig examines in his Pure mathematics study include Class, Bounded function, Group and Time–frequency analysis. His research in Mathematical analysis is mostly concerned with Fourier transform.

His Modulation space study results in a more complete grasp of Algebra. His studies deal with areas such as Convolution and Operator theory as well as Algebra. He has researched Combinatorics in several fields, including Lambda, Invariant and Entire function.

He most often published in these fields:

  • Pure mathematics (36.29%)
  • Mathematical analysis (25.00%)
  • Modulation space (18.15%)

What were the highlights of his more recent work (between 2017-2021)?

  • Pure mathematics (36.29%)
  • Combinatorics (11.69%)
  • Fourier transform (10.89%)

In recent papers he was focusing on the following fields of study:

His main research concerns Pure mathematics, Combinatorics, Fourier transform, Hilbert space and Modulation space. Pure mathematics connects with themes related to Time–frequency analysis in his study. His Combinatorics research is multidisciplinary, relying on both Lambda, Gaussian and Invariant.

His research in Fourier transform intersects with topics in Zero, Bessel function, Exponential function and Zero set. The Hilbert space study which covers Linear subspace that intersects with Bergman space, Hardy space, Analytic function, Variable and Operator norm. His Modulation space research includes elements of Space, Embedding, Uniqueness and Initial value problem.

Between 2017 and 2021, his most popular works were:

  • Sampling theorems for shift-invariant spaces, Gabor frames, and totally positive functions (30 citations)
  • Harmonic Analysis in Phase Space and Finite Weyl-Heisenberg Ensembles. (13 citations)
  • Orthonormal bases in the orbit of square-integrable representations of nilpotent Lie groups (9 citations)

In his most recent research, the most cited papers focused on:

  • Mathematical analysis
  • Algebra
  • Hilbert space

His primary scientific interests are in Fourier transform, Pure mathematics, Zero set, Exponential function and Short-time Fourier transform. His study in the field of Fourier analysis also crosses realms of Stability. His studies in Pure mathematics integrate themes in fields like Fock space, Kernel and Interpolation.

His Zero set research is multidisciplinary, incorporating elements of Zero and Bessel function.
