On complemented subspaces and unconditional bases in
On complemented subspaces of some Köthe spaces of infinite type.
On complete, precompact and compact sets.
Completeness criterion of W. Robertson is generalized. Applications to vector valued sequences and to spaces of linear mappings are given.

On completely continuous maps from locally convex spaces to l1.
On completions of LB-spaces of Moscatelli type.
On complex -predual spaces.
On Congruences and Cones.
On contraction-type mappings on a 2-normed space
On Co-Semigroups of Lattice Homomorphisms on a Banach Lattice.
On Countable Strict Inductive Limits.
On De Blasi's differentiation theory for multifunctions
On decomposition in barrelled spaces
On differences of Riesz homomorphisms.
On discrete subspaces of a Hilbert space
On Dragilev type power Köthe spaces
A complete isomorphic classification is obtained for Köthe spaces such that ; here χ is the characteristic function of the interval [0,∞), the function κ: ℕ → ℕ repeats its values infinitely many times, and . Any of these spaces has the quasi-equivalence property.
On equilibrium point in topological vector spaces
On exact sequences of quojections.
We give some general exact sequences for quojections from which many interesting representation results for standard twisted quojections can be deduced. Then the methods are also generalized to the case of nuclear Fréchet spaces.
On exhaustive vector measures.
On exposed semigroup homomorphisms.
