Direct algebraic operational calculi for functions u(x, y, t), continuous in a domain
of the form D = [0, a] × [0, b] × [0, ∞), are proposed. Along with the classical
Duhamel convolution, the construction uses also two non-classical convolutions for
the operators ∂2x and ∂2y. These three one-dimensional convolutions are combined
into one three-dimensional convolution u ∗ v in C(D). Instead of J. Mikusi´nski’s
approach, based on convolution fractions, we develop systematically an alternative
approach, based on the multiplier fractions of the convolution algebra (C(D), ∗). *2000 Mathematics Subject Classification: 44A35, 44A45, 35K20, 35K15, 35J25.
