1 Historical remarks
Toeplitz operators have been studied by analysts for many years. In [17] a Toeplitz operator on
S1 = {z ∈ C| |z| = 1} is defined as follows. Denote by µ the normalized Lebesgue measure,
and by en = en(z) = zn, z ∈ S1, n ∈ Z. Functions en are bounded, measurable, and they form
an orthonormal basis in L2 = L2(S1, µ). A function f ∈ L2 is called analytic if
∫
S1 fēndµ = 0
for all n < 0, and the Hardy space H2 is defined as the space of all functions in L2 which are
analytic. Denote by P : L2 → H2 the orthogonal projector. Let ϕ be a bounded measurable
function on S1. The corresponding Toeplitz operator Tϕ : H2 → H2 is defined by Tϕ = P ◦Mϕ,
where Mϕ is the operator of multiplication by ϕ. The function ϕ is called the symbol of Tϕ. We
immediately observe: for ϕ(z) = 1 Tϕ is the identity operator, and for α, β ∈ C and bounded
measurable functions f, g on S1 we have: Tαf+βg = αTf + βTg. These operators have various
remarkable properties. For example, Theorem 4 [17] states: A necessary and sufficient condition
that an operator on H2 be a Toeplitz operator is that its matrix (with respect to the orthonormal
basis {en : n = 0, 1, 2, . . . }) be a Toeplitz matrix.
Remark 1. Otto Toeplitz (1881–1940) was a German born Jewish mathematician, professor
in Bonn from 1928 until 1935. A Toeplitz matrix is a one-way infinite matrix (aij) (i.e. i, j =
0, 1, 2, . . . ) such that ai+1,j+1 = aij . For example, the matrix of Te1 in the basis {en : n =
0, 1, 2, . . . } is
0 0 0 0 · · ·
1 0 0 0 · · ·
0 1 0 0 · · ·
0 0 1 0 · · ·

Toeplitz operators on bounded domains in Cn, n ≥ 1, (on various function spaces) have been
studied extensively, and it would be a very difficult task to give a comprehensive description of

all the work done in this area. See, in particular, [11, 24, 25, 30, 31, 33, 34, 38, 40, 45, 46, 47,
48, 49, 50, 51, 52], and references in [11].
The purpose of this paper is different: we outline how Toeplitz operators appear in complex
and symplectic geometry (often in problems coming from mathematical physics) and we overview
some recent results in this area.
2 Kähler manifolds, geometric quantization
and Toeplitz operators
2.1 Preliminaries
The use of Toeplitz operators in geometric quantization has its origins in work of F. Berezin,
L. Boutet de Monvel, and J. Sjöstrand, see, in particular, [1, 2, 3, 12, 15, 16], and see also [37, 44].
Many of the key ideas are contained in [12]. The article [16] laid down the foundations for
the analysis. Other important, more recent, papers include [4] and [14].
In the following “smooth” will always mean C∞. Let W be a strictly pseudoconvex domain
in a complex n-dimensional manifold, n ≥ 1. Assume that the boundary ∂W is smooth and
W = W ∪ ∂W is compact. Let r ∈ C∞(M) be a defining function for W : r|W < 0, r|∂W = 0,
dr 6= 0 near ∂W . Let j : ∂W ↪→ W be the inclusion map. The 1-form α = j∗Im(∂r) is a contact
form on ∂W . Denote by ν the measure on ∂W associated to the (2n− 1)-form α∧ (dα)n−1, and
denote L2 = L2(∂W, ν). Denote by A(W ) the space of functions on W which are continuous
on W , smooth on ∂W , and holomorphic on W . Define the Hardy space H2 = H2(∂W ) to be
the closure in L2 of {f |∂W | f ∈ A(W )}. Denote by Π : L2 → H2 the orthogonal projector.
By definition an operator T : C∞(∂W ) → C∞(∂W ) is called a Toeplitz operator of order k
if it is of the form ΠQΠ, where Q is a pseudodifferential operator of order k. The symbol of T
is σ(T ) := σ(Q)|Σ (a function on Σ), where σ(Q) is the symbol of Q and
Σ = {(x, ξ) |x ∈ ∂W, ξ = rαx, r > 0}
is a symplectic submanifold of T ∗∂W . Note that the symbol is well-defined: if Q1, Q2 are
pseudodifferential operators and T = ΠQ1Π = ΠQ2Π, then σ(Q1)|Σ = σ(Q2)|Σ. Boutet de
Monvel and Guillemin also show that for Toeplitz operators T1, T2 σ(T1T2) = σ(T1)σ(T2),
σ([T1, T2]) = {σ(T1), σ(T2)}, where {·, ·} is the intrinsic Poisson bracket on the symplectic mani-
fold Σ, and Toeplitz operators form a ring under composition.
2.2 Berezin–Toeplitz quantization
Let X be a connected compact n-dimensional Kähler manifold, n ≥ 1. Denote the Kähler
form by ω. Assume that ω is integral. There is an (ample) holomorphic Hermitian line bundle
L → X, with Hermitian connection ∇, such that curv(∇) = −2πiω (thus c1(L) = [ω]). Let N
be a positive integer. We shall denote by L2(X, L⊗N ) the space of square-integrable sections
of L⊗N , and by H0(X, L⊗N ) the space of holomorphic sections of L⊗N . Also denote by C∞(X)
the space of real-valued smooth functions on X and by C∞
C (X) the space of complex-valued
smooth functions on X.
The unit disc bundle W in L∗ is a strictly pseudoconvex domain. Denote P = ∂W (the unit
circle bundle in L∗). In this particular setting, with k = 0, the definition of a Toeplitz operator
in Section 2.1 leads to the following (revised) definition. Let f ∈ C∞
C (X). The corresponding
Toeplitz operator (also called Berezin–Toeplitz operator in this setting) is

is the orthogonal projector.
Much has been written on this subject, see, in particular, review papers [7, 41, 43].
We shall list some properties of Berezin–Toeplitz operators. For every N the map

2.3 Other aspects
2.3.1. There is a strong connection between Berezin–Toeplitz quantization and deformation
quantization. See, in particular, [8, 18, 29, 32, 35, 36, 39, 42].
2.3.2. Everything discussed in Section 2.2 has a traditional “translation” into the language of
physics: it is customary to say that X is the classical phase space, 1/N is the Planck’s constant,
H0(X, L⊗N ) is the space of wave functions, f is a classical Hamiltonian, T
(N)
f is the quantum
Hamiltonian, and N → +∞ is the semiclassical limit. There are interesting and difficult results
related to semiclassical behaviour of eigenvalues and eigenfunctions of Toeplitz operators, to
quantization of maps, and, generally, to the relation between classical dynamics and quantum
dynamics. See, in particular, [9, 13, 53, 54, 55].
2.3.3. Symbol calculus of Toeplitz operators has been used to study integrable systems [5].
2.3.4. Lagrangian submanifolds and symplectic reduction are two very important concepts
in symplectic geometry. Toeplitz operators in this context have been studied and exploited
in [10, 19, 20, 21, 22].
4 T. Foth
2.3.5. Let (X, ω, J0) be a compact connected Kähler manifold (here X denotes the underlying
smooth manifold, ω is the symplectic structure, J0 is the complex structure). Denote by J the
space of all complex structures on X compatible with ω, it is an infinite-dimensional Kähler
manifold. The group Symp(X, ω) acts on J by pull-back. It was observed by Fujiki [28] and
by Donaldson [23] that J → sJ , where J ∈ J and sJ is the scalar curvature of the Riemannian
metric given by ω and J , is a moment map for this action. In [27] we obtain another proof of
this statement, using Toeplitz operators and semiclassical asymptotics.
