Graded Witt kernels of the compositum of multiquadratic extensions with the function fields of Pfister forms
It is known from a famous paper by \textit{K. Kato} [Lect. Notes Math. 967, 215--238 (1982; Zbl 0506.12022)] that differential forms play an important role in the theory of quadratic forms over fields of characteristic 2. They are heavily used in the present paper. But the authors also mention the recent paper of \textit{D. W. Hoffmann} (which appeared in [Proc. Am. Math. Soc. 143, No. 12, 5073--5082 (2015; Zbl 1414.11050)]), where part of their results are obtained without using differential forms.
